Optimizing outpatient total hip arthroplasty: perspectives of key stakeholders

Background Advances in surgical techniques combined with multimodal analgesia and early rehabilitation have potentiated early mobilization in patients undergoing total hip arthroplasty (THA). Given an increasing push from patients to accelerate recovery and health care budgetary limitations, there has been growing interest in the implementation of outpatient THA in selected patients. Understanding the patient and primary caregiver experience of outpatient THA is important to optimize care. We aimed to gain insight into patient and caregiver perspectives regarding the perceived advantages and disadvantages of same-day discharge to identify areas of care that can be improved. Method Using a qualitative descriptive approach, we conducted in-depth semistructured interviews with patient-primary caregiver dyads who experienced same-day discharge or standard care after primary THA with the direct anterior approach in 2016-2017. Two members of the research team coded the data independently, implementing a thematic and content analysis. Results Twenty-eight participants (16 same-day discharge, 12 standard care) were included. Both groups experienced high levels of satisfaction with their care pathway. Concerns and challenges identified in both groups pertained to mobility, pain, self-care and caregiver support. Challenges and concerns unique to same-day discharge were identified regarding expectations for recovery, medications and their impact on mobility, the timing of postoperative education and the availability of formal care. Conclusion Outpatient THA can be implemented with high patient and caregiver satisfaction. Preoperative education, clarification of recovery processes and expectations, and proactively addressing concerns related to caregiving are important

Species of Fungi in the Root System of Woody Plants in Urban Plantations

The features of the species composition of microscopic fungi in the root system and rhizosphere soil of woody plants in connection with the level of soil contamination have not been studied sufficiently. This article presents the results of studying the species composition of fungi in the root system and soil of three species of woodyplants (Acer negundo L., Acer platanoides L., and Betula pendula Roth.) growing in urban plantations of various ecological categories with different levels of heavy metal soil contamination. The study was carried out in a large industrial center of the Urals region, Izhevsk. When studying the species composition of fungi, microscopyand molecular genetic analysis were used. Isolates of endotrophic fungi from the root system of plants were isolated, and systematic membership was determined by molecular genetic analysis. The results showed that in soils with a high level of contamination, the DNA of endotrophic mycorrhiza-forming fungi was found in theroots of woody plants in a good living state. Keywords: fungi, heavy metals, plantations, urban environment, resistanc

Effect of Lignosilicon on the Content and Antioxidant Activity of the Polyphenols of Buckwheat Fagopyrum esculentum Moench

Lignin preparations, introduced into soil jointly with buckwheat Fagopyrum esculentum Moench, variety 'Aiva' (cultivated throughout Latvia) seeds during the sowing in quantities of 20 kg ha-1 and 40 kg ha-1, exerted a favourable effect on the ned in alcohol extracts from the biomass of different morphological parts of buckwheat, were represented mainly by rutin. The content of rutin in the ethanol extracts from the biomass of flowers with bract reached the maximum values in the phase of accomplishing blooming - beginning of fruit formation to be 2.74% in terms of dry mass (exceeding the rutin content development of plants and the synthesis of flavonoids in flowers with bract. Flavonoids, determin the control by 65%) in the variant with 40 kg ha-1 of Lignosilicon. Lignin preparations favoured the increase in the radical scavenging capacity of the alcohol extracts of the biomass of flowers with bract of buckwheat, as well as grain and hulls. The increment of the buckwheat grain crop, in comparison with the control on the background of 40 kg ha-1 of lignin, was 12%, and that on the background of 20 kg ha-1 and 40 kg/ha of Lignosilicon 10% and 15%, respectively

Legal Triggers for Digitalization of Radioactive Waste and Spent Fuel Management within the European Union

The article examines the impact of digitalization on radioactive waste and spent fuel management in the EU. The purpose of the research is the legal mechanisms that launch new digital technologies to improve radioactive waste accounting and control over its management. To set the goals of the research, such methods of scientific knowledge as logical, system-structural and comparative legal analysis were used. New EU legal documents (EC Digital Strategy 2018 and Shaping Digital Future of Europe 2020) have triggered process digitalization in the EU. According to analysis the EU legal acts, the authors came to the conclusion that the EU Commission principles of digitalization are security, confidentiality, openness, transparency and simultaneity. EURATOM successfully applies digital 3D technology and simulation for dismantling planning of nuclear facilities. In turn, the European Commission uses digitalization applies to data collection and radioactive waste and spent fuel management in the EU Member States. In conclusion, it is determined that the EU has not yet adopted artificial intelligence act for radioactive waste and spent fuel management. However, the EU already has some experience. In the future the EU can adopt a new legal act that will summarize all the practice of the EC, EURATOM and EU Member States to regulate of digitalization in the EU radioactive waste management

Eritrocytic Parameters of the Blood of Calves with Different Birth Weights

In the conditions of a dairy farm with the help of the standard clinical, instrumental and laboratory methods the research on particularities of Eritrocytic parameters of the blood of calves (n=299) with different birth weights was carried out. It is shown that Holstein calves with normal intrauterine growth, born with body weight from 36.5 to 29 kg, have no reliable differences in red blood cell count. With a 1 kg reduction in body weight, there is a trend towards hyperchromia, but an increase in weight deficiency promotes of hypovolemia, hypochromia, and polycythaemia. In newborns with a body weight of 27.9–26.9 kg, polycythaemia is derived from hypovolemia, but, with a more pronounced weight deficiency, the role of erythrogenesis disorder in the pathogenesis of the syndrome increases. Hypochromia is a consequence of hematopoietic organs dysfunction and transmembrane loss of hemoglobin. Herein membrane destruction is caused by the increase in the content of toxical metabolites in the blood (sorptivity of red blood cells by 10–12 percent), and by a higher level of adrenaline (modification coefficient of membranes by adrenaline by 20–30 %). This indicates that the response of the fetus to the factors that inhibit its development is similar to a metabolic response against stress. At strong underweight body (b.w. less than 25 kg) exhausting of adaptive capability is observed with the increase in the blood level of toxical metabolites (sorptivity of red blood cells by 15 %), level of membrane destruction (level of ectoglobular hemoglobin in 2,8 times), and heterogeneity of red blood cells. Thus, in newborns with a body weight of less than 29 kg, the significant disturbances in the structure and functions of red blood cells were revealed, which gave grounds for stating that they had antenatal hypotrophy. Herewith, the severity of hematological changes depends on the degree of weight deficiency. Initially, it is hypovolemia and the resulting polycythemia, but, erythropoiesis disorders, and destruction of their membranes with increased polycythemia, and the development of hypochromia occur with the increasing severity of hypotrophy

Cryptic Diversity in Paramecium multimicronucleatum Revealed with a Polyphasic Approach

Paramecium (Ciliophora) systematics is well studied, and about twenty morphological species have been described. The morphological species may include several genetic species. How-ever, molecular phylogenetic analyses revealed that the species diversity within Paramecium could be even higher and has raised a problem of cryptic species whose statuses remain uncertain. In the present study, we provide the morphological and molecular characterization of two novel Paramecium species. While Paramecium lynni n. sp., although morphologically similar to P. multimicronucleatum, is phylogenetically well separated from all other Paramecium species, Paramecium fokini n. sp. appears to be a cryptic sister species to P. multimicronucleatum. The latter two species can be distinguished only by molecular methods. The number and structure of micronuclei, traditionally utilized to discriminate species in Paramecium, vary not only between but also within each of the three studied species and, thus, cannot be considered a reliable feature for species identification. The geographic distribution of the P. multimicronucleatum and P. fokini n. sp. strains do not show defined patterns, still leaving space for a role of the geographic factor in initial speciation in Paramecium. Future findings of new Paramecium species can be predicted from the molecular data, while morphological characteristics appear to be unstable and overlapping at least in some species
