Aim. To identify whether the addition of red blood cell distribution width (RDW) could improve the Global Registry of Acute Coronary Events (GRACE) risk score 2.0 in patients with acute myocardial infarction (AMI).Material and methods. This prospective observational study included 577 AMI patients who underwent coronary angiography within 24 hours after symptom onset. Admission RDW was measured as part of the automated complete blood count. GRACE 2.0 score at admission was calculated. The clinical endpoint was 18-month all-cause mortality. Logistic regression analysis was used to identify predictive values of RDW. Area under the receiver-operator characteristic (ROC) curve (AUC), net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were calculated to evaluate the increment of predictive value for the combination of RDW with GRACE 2.0 score in predicting clinical adverse outcome.Results. The median age of patients was 65 (interquartile range: 56-74) years, while 60,7% were male. During 18-month follow-up, 66 patients (11,4%) died. RDW was positively correlated with GRACE 2.0 score (r=0,16, p<0,001). Multivariate analysis showed that both GRACE 2.0 score and RDW were independent predictors of 18-month mortality (odds ratio 1,025; 95% confidence interval [CI] 1,013-1,037; p<0,001; and 1,298; 1,087-1,551; p=0,004; respectively). The AUC for predicting 18-month mortality of GRACE 2.0 score, RDW and their combination was 0,795 (95% CI: 0,734-0,856), 0,708 (95% CI: 0,642-0,775) and 0,826 (95% CI: 0,775-0,876), respectively. Addition of RDW in the GRACE 2.0 score enhanced NRI (0,428; p=0,0009) and IDI (0,014; p=0,002).Conclusion. Baseline RDW levels at admission was associated with 18-month mortality in patients with AMI. The inclusion of RDW into GRACE 2.0 score enables more accurate prediction of long-term risk of death compared with GRACE 2.0 score alone.

One hundred patients with functional class III-IV CAD, stage I-IIa heart failure with LV ejection fraction (EF) >40%, successful coronary artery bypass grafting, SYNTAX Score of 33. During hospitalization, echocardiography, matrix metalloproteinase 9 (MMP-9), tissue inhibitor of metalloproteinase 1 (TIMP-1), monocyte chemoattractant protein 1 (MCP-1) were studied, while systemic immune-inflammation index (SII) was estimated. After 6 months, echocardiography revealed a group of patients with a decrease in LVEF.Results. The following factors of decreased LVEF were identified: type 2 diabetes, chronic kidney disease (p<0,001), >4 comorbid diseases (r=-0,597, p<0,001), increase in SII by 44,6% (p<0,001), MMP-9 by 62% (p<0,001), MCP-1 by 55,1% (p<0,001), TIMP-1 by 45,8% (p<0,001). An inverse relationship was found between LVEF and the level of SII (r=-0,626, p<0,001), MCP-1 (r=-0,747, p<0,001), MMP-9 (r=-0,718, p<0,001). There were following threshold values for predicting a decrease in LVEF: SII — 356,43, MMP-9 — 318,7 ng/ml, MCP-1 — 459,6 pg/ml.Conclusion. There are following markers of decreased LVEF in patients with CAD 6 months after successful coronary artery bypass surgery: type 2 diabetes, chronic kidney disease, >4 comorbid diseases, SII, MMP-9 and MCP-1 with a threshold value of 356,43, 318,7 ng/ml and 459,6 pg/ml, respectively.
Legal Basis of External Fiscal and other Payments of an Unrecognized State: Taiwan’s Experience
Authors: Shepenko R. A. 
Published: September 2024

Fiscal and other payments are divided into internal and external, which are subject to certain legal regulation. External fiscal payments are applied when goods are moved across the customs border of the state (territory).Since the status of a subject of international law depends on the attitude (decision) of other States and territories, it is natural to assume that in the case of an unrecognized state there is some specificity of the legal foundations and composition of external fiscal and other payments.This is true, but in terms of legal regulation, it is obvious that due to the lack of recognition as a subject of international law, some territories have a limited number of individual sources, for example, trade agreements.An unrecognized state may be a member of an international organization. Apparently, being within the global trading system is important for the composition of external fiscal and other payments, but not for the legal framework. In the given article, an attempt to comprehensively consider the legal foundations, as well as the composition of external fiscal and other payments of the Republic of China (Taiwan), with the identification of features accompanying the status of an unrecognized state, is made.

Celem artykułu było porównanie streszczeń tego samego tekstu – artykułu naukowego Jerzego Bartmińskiego pt. „Styl potoczny”. 35 streszczeń zostało wykonanych ręcznie, 5 to rezultat streszczania maszynowego (wykorzystano: Resoomer, Smodin, ChatGPT). Analiza wykazała, że streszczenia przygotowane ręcznie spełniają wymóg informacyjności, jednak jej stopień jest zindywidualizowany – uzależniony od kompetencji autora. W streszczeniach tradycyjnych trafniej identyfikowano kluczowe elementy treści i skuteczniej unikano umieszczania informacji drugorzędnych. Botowi ChatGPT udało się tego dokonać w mniejszym stopniu niż człowiekowi, ale otrzymane wyniki dają wgląd w treść artykułu. Streszczenie otrzymane przy pomocy programu Resoomer wymaga dodatkowej pracy (uzupełnień, redakcji). Efekt pracy narzędziem Smodin trudno uznać za tekst. Każde ze streszczeń ręcznych jest inne, podobnie jak streszczenia generowane przez ChatGPT. Streszczenia wygenerowane przez Resoomer i Smodin są zawsze takie same. Widać więc pewne podobieństwo nowoczesnego streszczania automatycznego do sposobu streszczania przez człowieka (a nawet różnych ludzi), którzy są w stanie wygenerować różne, poprawne streszczenia tego samego tekstu.

Selection of internal design of crystallizer sleeves for continuous casting of 200 mm billets
Authors: Bondarenko I. A. , Volodkin P. V. , Kovaleva I. A. 
Published: September 2024

The crystallizer is the most critical and most important functional unit of a continuous casting machine (hereinafter referred to as CCM). It is the main technological unit of the CCM, an assembly for removing heat during the solidification of the solidifying metal and the formation of the ingot. The main requirement for the crystallizer is to provide maximum heat removal from the solidifying steel to the cooling water, and to obtain a strong ingot shell with a good surface at the outlet of the crystallizer, which would not be destroyed by the heat of the liquid phase and the ferrostatic pressure. During the reconstruction of the CCM by the contractor company, drawings of crystallizers and crystallizer sleeves with a double‑cone internal geometry for casting 200 mm continuous cast billets were developed. The 200 mm continuous cast billet is a billet for the production of hot‑rolled seamless steel pipes. During the operation of the crystallizer sleeves with a double‑cone internal geometry, an accelerated wear of the protective coating in the lower part of the sleeve was noted, as well as an increased rejection of hot‑rolled pipes due to defects on the outer surface of the pipes. In order to identify the cause of the defect formation, complex metallographic studies of the outer surface of the pipes were carried out. As a result of the metallographic study, surface defects classified as steel mill scale on the outer surface of the pipes were identified. To minimize the “steel mill scale” defect and reduce the wear of the protective coating of the crystallizer sleeves, work was carried out to select the optimal conditions for the crystallization of the continuous cast billet: the use of crystallizer sleeves with a three‑cone internal geometry compared to a double‑cone was investigated; maintaining the temperature difference of the water at the inlet and outlet of the crystallizer within specified limits (ΔT) was tested. It was found that the use of a crystallizer sleeve with a three‑cone internal geometry for casting 200 mm billets and the stable behavior of the ΔT parameter made it possible to ensure the required quality of the surface of seamless pipes, reduce the wear of the protective coating of the crystallizer sleeves and increase the productivity of the CCM.

Many industrial enterprises use electroplating processes that lead to the formation of water containing heavy metal ions such as chromium, copper, zinc, nickel, and others. Such water is a dangerous source of environmental pollution. Most heavy metal ions belong to hazard classes I–II, they have carcinogenic and mutagenic properties, and have a cumulative effect.The literature analysis showed that there is positive experience in the use of steelmaking slags in the processes of cleaning contaminated water of various origins from heavy metals.The study examines the effect of acid activation on the adsorption‑structural characteristics of filtering materials created based on steelmaking slag. It is shown that during the interaction of some acids with slag, new crystallographic phases are formedon its surface, and contact with other acids leads to the leaching of ions and their transition to the aqueous phase. It has been established that during acid activation, the specific surface area increases by 57–132 times compared to the original material.

A numerical model of microplastic erosion, transport, and deposition for fluvial systems
Authors: Armitage John Joseph , Rohais Sébastien 
Published: September 2024

Abstract

Rivers are the primary pathway of microplastic pollution from source to the eventual sink in the marine environment. However, like sediments, microplastic will become trapped within the fluvial system as it makes its way from source-to-sink. There is therefore the potential that rivers are an important reservoir of microplastic pollution globally. To explore the transport of microplastic through the fluvial system we develop a reduced complexity model of microplastic erosion, transport, and deposition that builds on methods developed for the transport of sediment. We apply this model to the river Têt, France, where there has been punctual monitoring of the flux of microplastic at the outlet. We find that the reduced complexity model captures the observed quantity of microplastic under reasonable assumptions of the relationship between microplastic sources and population density. The model that best matches observed fluxes of microplastic at the outlet of the Têt river requires between 1 and 10 ppm volume concentration of microplastic per 200×200 m in the top half a meter of soil. The microplastic of grain size 300 μm then travels within the river network with a settling velocity of the order of 10-4 m/sec. The model results imply that a large proportion of microplastic will become entrained within the sediments along the fluvial system. This model is a first step in assessing where to sample for microplastic pollution within fluvial systems and points to regions susceptible to microplastic pollution.

Abstract

The marked seasonality of temperate habitats in food availability and requirements of energy expenditure in reproduction or temperature homeostasis affects most aspects of wild animals, including meat composition. This study examines for first time the effects of seasonality (assessed as hunting month: September, January, April, and June) on loin muscle quality from 32 adult wild male deer culled stress-free. Deer hunted in September (end of summer) had the highest carcass weight and yield, while the lowest values were observed in January (mid-winter) and June (beginning of summer; p < 0.001). Intramuscular fat content was also higher in September than in the other months, but differences were only significant with April (p = 0.016). Other seasonal effects were found for pH72, shear force and fatty acid composition (p < 0.05). In contrast to these differences, likely caused by food availability, meat mineral composition seems to be caused by the mineral mobilization from the skeleton to grow antlers, as Ca and Mg were higher in April, and Fe and Zn were lower in this month and June. Thus, we can conclude that both, the season and the effort to grow antlers, affecte6d the meat quality and composition in wild male red deer.

Abstract

Edible insects are a compelling alternative source of animal protein that holds potential for diversifying and enriching complementary foods with minerals and proteins. This study aimed at formulating, developing and characterizing nutrient- dense complementary flour (CF) containing edible cricket containing maize and roasted finger millet flours (CECF). In addition, the effect of extrusion was evaluated on nutritional, functional and microbiological properties. Analysis of variance (ANOVA) with multiple comparisons using Tukey’s HSD (honestly significant difference) test (α = 0.05) and T- test were used to determine the significance of differences. Edible cricket had significantly high protein, fat, chitin/fibre, energy, iron, zinc and phosphorus. Contrary, cereal flour had high total carbohydrates, manganese and calcium. Phytates were undetectable in roasted finger millets but tannins remained highest at 494.1 mg/ 100g. Extrusion of CECF significantly (p > 0.05) improved the energy ration and densities of protein, carbohydrate but decreased the energy content and fibre content and density. Extrusion reportedly eliminated the phytates and reduced tannins content to acceptable levels for infant foods. Iron content were increased (4.64–6.22 mg/ 100g), whereas Ca: P remained low at 0.35–0.36. Extruded and blended CECFs had poor foaming and emulsion properties. Extrusion improved swelling power, bulking density and water related properties as well as protein digestibility. Microbial quality of the CECF was influenced by the initial microbial load, cross contamination and pre-processing conditions. The study suggests inclusion of edible cricket, pre-processing of ingredients, extrusion and a possible final cooking of CECF as well as observing hygienic and sanitary conditions for a safe and nutrient dense infant food. Further research is needed on evaluating the acceptability and the impact of feeding CECF on children’s growth and development.
Hyperuricemia and gout as uncommon manifestation of Papillorenal syndrome in an 18-year-old young man with PAX 2 mutation : A Case report and review of the literature
Authors: Rajae Boutaleb , Axel Derwa 
Published: September 2024

Abstract

Hyperuricemia is a metabolic abnormality, either acquired or inherited, characterized by elevated levels of uric acid (UA) in the serum. We are interested in the case report regarding hereditary hyperuricemia. In this case, we are reporting on an 18-year-old man who experienced repeated gout attacks, hyperuricemia, and reduced fraction ejection of uric acid (FEUA). Additionally, he had renal anomalies such as proteinuria and renal hypoplasia and Focal and segmental glomerulosclerosis (FSGS) in the kidney biopsy and eye fundus revealed a bilateral optic disc pit .These findings prompted us to conduct a genetic study on the patient. To our surprise, the DNA sequence analysis did not detect mutations in UMOD or REN, which are commonly associated with familial juvenile hyperuricemic nephropathy (FJHN). Instead, a mutation in the paired box 2 (PAX2) gene was identified which is a very rare entity. We concluded that the patient had papillorenal syndrome (PAPRS) . Hyperuricemia is a rare and uncommon manifestation in patients with PAPRS and PAX2 mutation, and has only been documented in three studies in the literature. The diagnosis of PAPRS is often underestimated and not well-known by clinicians. It exhibits high clinical variability and phenotypic heterogeneity without well-defined diagnostic criteria. The presence of hyperuricemia should prompt consideration of this diagnosis and it should be included in the diagnostic criteria for PAPRS in the future.
