Abstract Introduction: Acute kidney injury (AKI) in the setting of COVID-19 is associated with worse clinical and renal outcomes, with limited long-term data. Aim: To evaluate critically ill COVID-19 patients with AKI that required nephrologist consultation (NC-AKI) in a tertiary hospital. Methods: Prospective single-center cohort of critically ill COVID-19 adult patients with NC-AKI from May 1st, 2020, to April 30th, 2021. Kidney replacement therapy (KRT), recovery of kidney function, and death at 90-day and 1-year follow-up were evaluated. Results: 360 patients were included, 60.6% were male, median age was 66.0 (57.0–72.0) years, 38.1% had diabetes, and 68.6% had hypertension. AKI stages 1, 2, and 3 were detected in 3.6%, 5.6%, and 90.8% of patients, respectively. KRT was indicated in 90% of patients. At the 90-day follow-up, 88.1% of patients died and 10.0% had recovered kidney function. Female gender (p = 0.047), older age (p = 0.047), AKI stage 3 (p = 0.005), requirement of KRT (p < 0.0001), mechanical ventilation (p < 0.0001), and superimposed bacterial infection (p < 0.0001) were significantly associated death within 90 days. At 1 year, mortality was 89.3%. Amongst surviving patients, 72% recovered kidney function, although with significantly lower eGFR compared to baseline (85.5 ± 23.6 vs. 65.9 ± 24.8 mL/min, p = 0.003). Conclusion: Critically ill COVID-19 patients with NC-AKI presented a high frequency of AKI stage 3 and KRT requirement, with a high 90-day mortality. Surviving patients had high rates of recovery of kidney function, with a lower eGFR at one-year follow-up compared to baseline.

Published: January 2025

The mite Varroa destructor Oudemans, 1904 (Acari: Varroidae) is a major contributor to honeybee colony losses worldwide. Actinobacteria are known for their wide distribution and production of biologically active compounds effective against various pathogens, including bacteria and parasites. This study aims to investigate the bioactive compounds produced by actinobacterial symbionts associated with Apis mellifera L., 1758 (Hymenoptera: Apidae) and evaluate their acaricidal potential against V. destructor. In 2022, a strain of Bifidobacterium sp. ERSapi20 was isolated from worker bees in Antalya, Türkiye, using a culture-based method. The antiparasitic activity of the extracellular solution and intracellular extract of the strain was assessed through direct spraying on V. destructor at varying concentrations of insect Ringer solution (0%, 25%, 50%, 75%, and 100%). The extracellular solution achieved 90% mite mortality within 16 hours, while the intracellular extract resulted in 100% mite mortality within 18 hours. This is the first report demonstrating acaricidal activity against V. destructor using intracellular extracts of actinobacterial strains. These findings support the hypothesis that honeybee-associated actinobacteria produce compounds effective against varroa mites, highlighting the potential of natural products for controlling V. destructor in honeybee colonies.

Published: January 2025

The high incidence of thrombotic complications has led to the widespread use of anticoagulant therapy and prophylaxis in patients with COVID-19 after recovery. One of the most vulnerable groups of the population in relation to COVID-19 are elderly and senile people. The purpose of the study – analysis of literature data on the study of the effectiveness of the use of anticoagulant drags in elderly patients who have had a viral infection COVID-19, with a history burdened by concomitant pathology. The review presents literature data on the effectiveness of the use of anticoagulant therapy in elderly patients after mild or moderate COVID-19 against the background of various somatic diseases. To correct coagulation hemostasis disorders in clinical practice, both time-tested «classic» drags (heparin, warfarin), which require periodic monitoring of the international normalized ratio, and new oral anticoagulants from the group of direct thrombin inhibitors (dabigatran or Pradaxa®) and the group of oral inhibitors of activated factor ten (Xa) activity – rivaroxaban (Xarelto®), apixaban (Eliquis®) and edoxaban (Lixiana®, Savaysa®, Roteas®) – which have gained wide popularity. The article describes options for anticoagulant and antiplatelet therapy for elderly patients who have had coronaviras infection with various concomitant pathologies (hypertension, coronary heart disease, atherosclerotic cardiosclerosis, thrombosis of cerebral vessels, deep veins of the lower extremities, atrial fibrillation, conditions after stent placement). An analysis of the literature shows that doctors are concerned about the increased risk of thrombotic complications in the new coronaviras infection COVID-19. Early initiation and correct administration of anticoagulant therapy for COVID-19 are an undoubted factor in improving the prognosis in a group of elderly, somatically compromised patients. It has been established that direct oral anticoagulants for the treatment of thrombotic complications after COVID-19 in elderly patients with various comorbidities have a number of advantages over classic drags of this group. They are available, have a convenient method of administration, a regimen for determining and adjusting the dose, and do not require periodic monitoring of the international normalized ratio.

The aim – to study the interrelation of cord blood level of vitamin D3 and interleukins (IL) -4, -8, -10 with the dose of vitamin D3 supplementation during pregnancy. The cord blood level of IL-4, -8, -10 and vitamin D3 have been studied in 119 newborns. Data have been analysis separately in dependence on taking of vitamin D3 –containing drags during pregnancy (group I - did not receive vitamin D3, group II-l received <400-500 UE/ml irregularly, II-2 and II-3 had 400-500 UE/ml and 800-120 UE/ml daily during pregnancy respectively). It has been shown refusal of vitamin D3 is associated with less it’s cord blood level and concentration of anti-inflammatory cytokines than in group II while proinflammatory IL-8 was significantly higher. It has been shown that refusal of vitamin D3 during pregnancy is associated the decrease of cord blood of it and proinflammatory cytokines. At the same time, there were higher dose-dependent increase of concentration of anti-inflammatory IL-4 and IL-10 in group II. The last is the key cytokine associated with immune tolerance requiring for maintenance of pregnancy, but activation of proinflammatory mechanisms may lead to pregnancy interruption.

Published: January 2025

Solvent extraction (SX) is a widely used separation and purification technique in hydrometallurgy, enabling the selective transfer of target metal ions between aqueous and organic phases. The process relies on chemical equilibrium and the interaction between metal ions and extractants in the organic phase. The free ligand (FL) model enhances the understanding of SX by focusing on the availability of free ligands in the organic phase, a critical factor influencing extraction efficiency and purity. The FL model to calculate the equilibrium concentrations in solvent extraction (SX) based on the distribution coefficient (Kd) at infinite dilution and the fraction of free ligand available for extraction. In this work, the FL model is validated to account for co-extraction of Ni and for designing the extraction and scrubbing sections of Co/Ni separation in a base metal refinery. Cyanex 272 is employed as a selective Co extractant in the process to yield high purity Ni. To enhance the loading capacity of the extractant, 50 mol% of NaOH is pre-loaded into it. Experimental and FL modelling results show that four equilibrium stages are required to purify the 99% Ni feed to a 99.97% Ni raffinate. The 53.59% co-extract with 26.76% free ligand is purified with a reflux scrub of 30 g Co/L in one equilibrium stage to 99.01%, Co in the scrubbed extract. The FL model as well as the Co/Ni/Na-analysis of the aqueous phase confirm that in the scrubbing section, Ni in the extract is mainly replaced by Co. Finally, in the one stage stripper the Co concentration in the scrubbed extract is increased from 5.6 g Co/L in the extract to 30.5 g Co/L that is partially used as reflux scrub liquor.
Removal of iron from vanadium redox flow battery electrolyte using ion exchange
Authors: Makonese M. , Sole K.C.
Published: January 2025

Bushveld Belco is commissioning a plant for production of electrolyte used in vanadium redox flow batteries. Owing to the source material, the electrolyte is contaminated with Fe, at concentrations up to 140 mg/L, which negatively affects battery performance. This study examined the use of ion exchange to reduce the Fe concentration to the target value of < 100 mg/L from a feed solution containing 100 g/L V in 4 M H2SO4. Four resins with possible application were identified: Puromet MTS9570, Puromet MTX7010, Puromet MTS9500, and Puromet MTC1600H. Puromet MTS9570 outperformed the other three resins in all batch experiments with respect to loading capacity and selectivity over V, and was evaluated for Fe removal in fixed-bed column loading tests. Based on these data, preliminary sizing and design of a full-scale column was undertaken. Owing to the difficulty of eluting this resin, a philosophy of discarding the resin on loading to full capacity was considered. These data revealed that, despite the high selectivity of this resin for Fe over V, it would be too expensive and impractical to use this resin for full-scale operation under such conditions. It is recommended to remove iron earlier in the flowsheet prior to generation of the 4 M H2SO4 electrolyte.

Published: January 2025

The article proposes to report on the development and discuss the results of a university extension project carried out among undergraduate and graduate students in Architecture and Urbanism and students from the 2nd stage of basic education in a public school on the outskirts of São Paulo city. The project aimed at sharing knowledge and practices regarding urban afforestation, tree species, and native birdlife. The initiative is justified by the understanding that planning and actions focused on sustainable urban design benefit from the participation of populations, while also revaluing ecosystems and integrating them into society has a real impact on local life, strengthening the sense of recognition and potentially providing lasting economic and environmental benefits. The activities involved literature review on native bird and tree species, holding discussion meetings with the school community, giving lectures on Brazilian flora and the animals attracted to them, and planting seedlings of native trees in the school's open area to start a garden. As a result of the project, based on the identified challenges, it is argued that environmental education practices involving the school community, related to the afforestation of native species, can be understood as: (I) a strategy for counter-colonization of knowledge; (II) a possibility for exploring multisensorial experiences; (III) a gesture of intergenerational and planetary responsibility; and (IV) the building of alliances and practicing the common.

Understanding the relationship between the built environment and human health has advanced significantly, highlighting the importance of considering physical, emotional and community aspects in urban planning. Housing satisfaction appears as a crucial element in this context, being closely linked to the well-being and quality of life of the inhabitants. Recognizing the diversity in individual perceptions, preferences, needs and evaluations, it is essential to adapt the residential environment to meet these variations. The effectiveness of the methodology and data collection instruments directly impacts the advancement of research on housing satisfaction. In this sense, the current study aimed to build and validate an assessment scale for elderly people's housing satisfaction, adopting an integrated and comprehensive approach. Using the e-Delphi method and counting on the participation of experts in the instrument's areas of interest, such as gerontology, architecture and housing, the results demonstrated that housing satisfaction is influenced by several factors, from physical characteristics of the home to social and demographic aspects. The resulting scale was organized into three main domains: Surroundings, Building and Singularities, subdivided into items that address both objective and subjective aspects of housing. These elements, together, contribute to configuring a built environment that plays a central role in promoting the satisfaction and well-being of residents, standing out as an essential component in the search for a more human and sustainable architecture.

The increasing popularity of snail meat prompts research of the nutritional benefits of consuming Helix aspersa maxima cultivated in Bulgaria. With a high protein content and remarkably low fat content, snail meat is well-suited for the inclusion in healthy culinary recipes. Daily consumption of snails meat, which is notably rich in iron, manganese, phosphorus, calcium, and magnesium, proves to be a valuable source of essential minerals. The fatty acid profile of Helix aspersa maxima is characterized by the diverse range of polyunsaturated fatty acids, with linoleic acid and arachidonic acid being the most abundant. The amino acid profile of the snail meat is characterized by significant levels of essential amino acids, with leucine, lysine and threonine contributing to protein synthesis, immune function, and tissue repair, respectively. The presence of large quantities of flavour-enhancing amino acids, such as glutamic acid and aspartic acid along with glycine, arginine, and proline, suggests a rich umami taste and supports collagen formation, and structural integrity.

Oils obtained from fruit and vegetable by-products represent a new category of niche oils. Cold-pressed oil from the seeds of sweet peppers of the Podravka and Slavonka varieties is a new, high-quality oil from the vegetable niche oil category, naturally rich in polyunsaturated linoleic fatty acid, γ-tocopherol, and sterols as antioxidants that exhibit positive effects on human health in preventing chronic non-communicable diseases. However, for a broader commercial reach of this oil, preserving its quality over a longer period is of utmost importance. Based on monitoring four parametres (peroxide value, free fatty acids, antioxidative power, and radical potential), pure pepper seed oil did not have adequate quality by the end of the period of 9 month stored at room temperature due to oxidative changes. The addition of natural antioxidants such as green tea extract (0.2%), especially rosemary extract (0.2%) and a blend of rosemary extract (0.2%), and citric acid (0.01%) extended the stability of pure pepper seed oil to a period of one year. Since oxidation affects the organoleptic quality and nutritional composition of the oil, these results are encouraging for niche oil producers, not only because of the expansion of this category of edible oils made from secondary source raw materials (by-products), but also because of the evidence that their special quality will not be compromised within the declared shelf life due to oxidative spoilage.
On the use of the Discrete Fourier Transform in Subdivision Schemes
Authors: Bityukov Y.I. , Bityukov P.Y.
Published: January 2025

The article is devoted to the development of the method of geometric modeling based on subdivision schemes and the application of this method to the parametric description of a surface or an area from a point cloud obtained by any method. To find the initial sequence of the scheme of subdivisions, the method of least squares is used, but its direct use is difficult due to the huge size of the matrices. Since subdivision schemes are based on sequence convolutions, a discrete Fourier transform is used to eliminate the matrix size problem, and the method of least squares is not the initial sequence itself, but its Fourier transform.

Este artigo traz um recorte da minha dissertação de mestrado “Leitores em (trans)formação: a crítica ao patriarcado em contos de Marina Colasanti”, em que se investigou a contribuição do ensino de literatura e suas interfaces frente à cultura do patriarcado, visando à formação do leitor crítico, por meio da recepção e análise de contos colasantianos. No presente texto, objetivou-se explorar dentro desse viés investigativo a relevância da leitura literária para a sensibilização e para a formação crítica, visando o desenvolvimento de habilidades leitoras de interpretação e de reflexão sobre a representação da violência contra a mulher. Teve como público, estudantes do 1º ano do Ensino Médio, de uma escola pública do município de Campo Verde-MT, no período de setembro de 2022, por meio da aplicação de uma Sequência Básica proposta por Cosson (2006). Em suma, observou-se que a leitura literária nas aulas de Língua Portuguesa promove o exercício da imaginação e da subjetividade, ao mesmo tempo que valoriza a experiência estética. Dessa forma, fica evidente que práticas educativas com o gênero conto fornece subsídios essenciais para questionar as relações de poder reforçadas por uma cultura machista e patriarcal, bem como ampliar as possibilidades interpretativas que favoreçam a descoberta prazerosa na leitura.

Abstract
This article presents an excerpt from my master's thesis “Readers in (trans)formation: the critique of patriarchy in stories by Marina Colasanti”, in which the contribution of teaching literature and its interfaces to the culture of patriarchy was investigated, aiming at the development of critical readers, through the reception and analysis of Colasantian short stories. In this text, the aim was to explore within this investigative framework the relevance of literary reading for raising awareness and developing critical thinking, aiming to develop reading skills of interpretation and reflection on the representation of violence against women. The audience were students in the first year of high school, from a public school in the city of Campo Verde-MT, in September 2022, through the application of a Basic Sequence proposed by Cosson (2006). In short, it was observed that literary reading in Portuguese language classes promotes the exercise of imagination and subjectivity, while valuing the aesthetic experience. In this way, it is evident that educational practices with the short story genre provide essential support for questioning the relations of power reinforced by a sexist and patriarchal culture, as well as expanding the interpretative possibilities that favor pleasurable discovery in reading.

Language Competence and Language Mediation Competence in Translation Studies and Language Teaching
Authors: Schmidhofer Astrid
Published: January 2025

In this article, I will compare the concept of mediation competence, its modelling and its relationship to language competence in Translation Studies and Language Teaching. While competence modelling has a long tradition in Translation Studies and focuses on describing the competences of professional translators (often opposed to bilinguals’ competence), mediation is a relatively new concept in Language Teaching, which was put on the map in the CEFR 2001. For my analysis, I will first describe areas of interest and relevant models in each discipline and then analyse the overlaps and differences as well as areas of contention.
Of Sphinx and Sparrows: The Apocalyptic Vision in Yeats’s “The Second Coming” and Milosz’s “A Song on the End of the World”
Authors: Nazari Hossein , Dashtizad Faezeh
Published: January 2025

This paper critiques the contrasting apocalyptic visions in Yeats’s “The Second Coming” and Miłosz’s “A Song on the End of the World”. Taking Yeats’s poem as the epitome of modern apocalyptic vision, we can dissect the differences between the mainstream view of the apocalypse in this era and the marginal one in Miłosz’s poem, which are represented in the imagery each poet creates. Consequently, the juxtaposition of the two poems leads to a more profound understanding of the competing formulations of apocalypse in the early twentieth century, which is more heterogeneous in nature than the literature of the period may initially suggest.
Demarcations in Soviet Central Asia in the 1920s and 1930s as a Manifestation of the Control of the Political Center over its Peripheries
Authors: Gil Andrzej
Published: January 2025

The demarcations carried out in Soviet Central Asia on Stalin's initiative were intended to organize the local ethnopolitical landscape and introduce social stabilization. The border changes were – according to the declaration of the Moscow center – also intended to lead to the best possible use of the region’s resources. In fact, however, the demarcations in Central Asia carried out in the 1920s and 1930s were aimed at breaking the unity of the local population around the idea of pan-Turkism. They introduced chaos and tensions between the nations that were in practice, leading to the creation of a conflict-generating situation. The tightening of the Bolshevik regime in the late 1930s slowed down these negative phenomena somewhat. However, they broke out with the crisis of the Soviet Union and the emergence of independent states in the former Soviet Central Asia.
Mykhailo Slabchenko and His Concept of „Corpus Juris Ukrainensis” Publication
Authors: Vashchuk Dmytro , Blashchuk Svitlana
Published: January 2025

The article focuses on one of the best specialists in the history of the state system of the Hetmanate and its legal institutions of the seventeenth and eighteenth centuries, Mykhailo Slabchenko. He wrote more than a dozen monographs, more than two hundred articles, became one of the founders of the national historical and legal science and a new academic subject, History of the State and Law of Ukraine, and launched new historical, legal, and socioeconomic areas of historical research. In 1925, he became a freelance employee of the Commission for Study of the History of Western-Ruthenian and Ukrainian Law of the AUAS (All-Ukrainian Academy of Sciences). He prepared and delivered a number of reports. At the end of 1928, M. Slabchenko submitted a report note to the Commission with a proposal to prepare and publish a corpus of documents on the history of Ukrainian law, the “Corpus juris ukrainensis”. M. Slabchenko proposed to prepare 16 volumes of the publication within 5 years, organized according to the chronological (in some cases, problematic and chronological) principle, starting with the treaties of Kyivan Prince Oleh with Byzantium (867) and ending with the legislative activities of the Soviet government until 1925. However, after discussion at the Commission, it was decided to limit the lower limit to 1917. Unfortunately, the plans could not be implemented due to the arrest of M. Slabchenko. The publication of this report note with a scholarly commentary serves as an appendix to the article.

The aim of the paper is to present the results of research on selected phenomena of the cultural heritage of shepherds in the Polish part of the Carpathians. Presented in the paper are the findings on the structure of the yearly and diurnal cycles manifested in the practice of shepherding, as well as the most important elements of the shepherds’ worldview.

In this paper, I used the results of qualitative research conducted at selected pastures in Spisz, Orawa, Podhale, the region of Żywiec and Silesian Beskids in Poland between 2015 and 2022. The research techniques applied include standardised and free-form interviews with master shepherds and their crews working in the pastures, as well as overt and covert participant observations carried out during selected shepherds’ holidays and meetings in different spaces – in churches, during highlander and Wallachian festivals, thematic meetings and in the pastures. The above techniques were supplemented with an analysis of the visual sources encountered during the field research, as well as those provided by enthusiasts of the subject and found on the Internet.

The research showed that modern pastoralism oscillates between two contrasting tendencies – tradition, through which it has retained many elements from the past, and modernity, through which the shepherds introduce solutions drawn from contemporary culture to their pastures. The yearly cycle of the shepherds’ life comprises two parts (seasons), during which they stay in different spaces and carry out work according to the rhythm of nature, influenced by the shepherds’ vision of the world and accompanied by their rich rituals.
The Church of St. John the Baptist in the Vlach Village of Orawka (the 17th century) – Identification of Tangible and Intangible Cultural Heritage Assets
Authors: Kocój Ewa , Borczuch Lucyna
Published: January 2025

The church of St. John the Baptist in Orawka, located close to the present-day Polish-Slovak border, is one the most valuable monuments of wood architecture. It is considered the oldest wooden monument in Orawa and a symbol of the region’s complicated history. Its heritage is a testament to the interacting cultures of different nations and ethnicities, among others: Vlach, Ruthenian, Hungarian, Slovak and Polish. This article’s objective is a new attempt at identification of assets of cultural heritage found in the church in Orawka. We present historical objects of art, as well as the iconographic program of the church’s interior. We also describe the main rituals and customs linked to the church, practiced by the local population to this day. In our research, we employed qualitative methods – analysis of historic and iconographic sources, as well as open-ended interviews, and participant observation conducted in the years 2015–2019 in the local community of Orawka. In the analysis of the material, we use both the perspectives of ethnography and cultural anthropology, supplemented with an input from other scientific disciplines and sub-disciplines, primarily history, historical anthropology, history of art and theology.
The City Plans of Łęczna from 19th Century. The Origins and Iconography
Authors: Jop Robert
Published: January 2025

This article discusses issues of cartographic sources documenting the history of Łęczna, i.e. the city plans and its fragments. Historians working on this topic have not expressed any increased interest in the matter. Their attention was focused on a plan from 1846, made after the fire in the city which took place on 10 November. The plan was published as one piece or in fragments, but mainly in order to draw the attention to the very fact of its existence, as an overall characterization of presenting Łęczna, or it was referred to while discussing various aspects of the town’s history. However, both in this case and in the case of other city plans, no source studies have even been made. The sources that are used come from the collection of the National Archives in Lublin, National Library, and the Central Archives of Historical Records in Warsaw.

While presenting individual plans, their origins and iconography was discussed. It should be stated that in this context, the cartography of Łęczna is rather poor. We have only six city plans. This results from the fact that the city was of little importance as an administrative, economic, and political centre, additionally being a private property. The plans that had been made consist primarily of the image of the city fragments, while the full plans, apart from the one from 1846, are rather schematic and simplified. This makes it impossible to capture the dynamics of spatial changes in the development of Łęczna in the 19th c.

The query was not of intentional nature. It was rather piecemeal. Therefore, one should not expect to find the plans of Łęczna as separate archival units in the known studies and reviews of archive collections. It is more likely that they could be found as attachments to various cases.
Not Only Enthusiasts – the Image of the January Uprising in Women’s Memories Based on the Accounts of Wanda Umińska, Emilia Heurichowa and her Daughter Teodora Kiślańska
Authors: Pająk Jerzy Zbigniew
Published: January 2025

This review article concerns critical editions of women’s memoirs of the 19th century compiled by Lidia Michalska-Bracha and Emil Noiński, concerning the period of the January Uprising. The memoirs of Wanda Umińska, and Emilia Heurichowa and her daughter Teodora Kiślańska are an important source both for the history of the uprising movement and for the history of women’s emancipation in the Polish lands in the 19th century. Both studies stand out from the rest because of the perfection of their preparation. They are accompanied by commentaries and editorial notes, as well as extensive footnotes and bibliographies. They are also equipped with personal and geographical indexes, which is not very common in this type of work. The commentaries provide an introduction to the issues contained in the memoirs and their positioning among other accounts of the period, while the editorial notes discuss the source basis and method of publication. Both critical editions of the memoirs broaden our knowledge of the post-January uprising, as well as the society of that period. It should also be emphasised that they are highly reliable, which was verified by the authors of the study.
Retinal Migraine: from History to the Present Day
Authors: Sheremet N. L.
Published: January 2025

Retinal migraine is a rare migraine variant, initially described in 1882 as ‘ophthalmic megrim’. Since then, various terms have been used in the literature, such as “ocular migraine”, “monocular migraine”, and “migraine of the anterior visual pathway”. The lack of an unified definition led to controversy and potential confusion in defining the diagnosis. Later, the International Classification of Headache Disorders (ICHD-3) defined retinal migraine as repeated attacks of monocular visual disturbance, including scintillation, scotoma or blindness, associated with migraine headache, which are fully reversible. Retinal migraine should be considered a diagnosis of exclusion that requires ruling out other causes of transient monocular vision loss. The purpose of this review is to analyze the data on the prevalence, pathogenesis, clinical presentation, and differential diagnosis of retinal migraine reported in the literature.
Evaluation of the Accuracy of IOL Calculation from the Standpoint of the Medical and Social Model of Health in Patients with Visually Intense Work and Bilateral Cataracts
Authors: Ovechkin N. I.
Published: January 2025

Purpose: to compare the accuracy of IOL calculation from the standpoint of the social model of health (based on the study of “quality of life”, QOL) in patients with visually intense work (VIW) and bilateral cataract.

Methods. We observed 108 patients with binocular cataract (216 eyes) aged 40 to 69 years (mean age 55.9 ± 1.4 years), everyday activities were characterized as VIW (at least 4 hours per day). All patients underwent (sequentially on both eyes) ultrasound phacoemulsification using the standard technique. All patients were operated on by the same surgeon (N.I. Ovechkin). To correct aphakia, a monofocal IOL “Flex HB Medicontur” (Switzerland) with a predicted emmetropic “target refraction” (TR) was implanted. All patients were divided into two groups: a group of patients (56 patients, 112 eyes) in which the IOL calculation was performed using the Kane formula (KF); a group of patients (52 patients, 104 eyes) in which the IOL calculation was performed using the Barrett Universal II formula (BU-II). The patients were examined 3 months after the second surgery based on a comparative study of refraction between the RC and the calculated one. The basic research method in relation to the target objectives of the work was a study of QOL using two questionnaires — Catquest-9SF and FEC22.

Results. The data obtained indicate an insignificant, statistically insignificant trend towards improvement in traditional refraction indices and QOL according to the Catquest-9SF questionnaire when calculating IOL using the KF compared to BU-II. At the same time, these differences in relation to the assessment of QOL using the FEK-22 questionnaire are characterized by pronounced (by 2.3 %), statistically significant (p < 0.05) differences.

Conclusion. The use (based on the original FEK-22 questionnaire) of the “medical and social” health model in the context of assessing the effectiveness of IOL calculation in VIW patients indicates a higher accuracy of the Kane formula compared to the Barrett Universal II formula. The identified differences are due to the fact that calculations using the Kane formula are performed in a comprehensive manner based on basic eye parameters, theoretical optics, regression analysis and, most importantly, artificial intelligence.

Objective. To develop a technique of hybrid photodynamic therapy (PDT) and present its preliminary results in combined organ-preserving treatment of uveal melanoma (UM).

Materials and methods. 4 patients with UM (T2aN0M0 — 2 patients, T3aN0M0 — 2 patients) were treated by hybrid PDT followed by Ru-106 + Rh-106 brachytherapy (BT). The initial UM prominence ranged from 7 to 8.6 mm (7.92 ± 0.67 mm), and the tumor base diameter ranged from 10.3 to 14 mm (12.10 ± 1.89 mm). PDT was performed using a chlorine photosensitizer at a rate of 1.0 mg/kg weight using a new hybrid technology, which consists of transpupillary and transscleral exposure to the tumor in one treatment session. Ru-106 + Rh-106 BT was performed according to the standard technique for up to 1 month after PDT.

Results. The combined approach contributed to rapid rates of tumor regression at the early terms of dynamic follow-up and achievement of complete regression at the period of 12 months in 2 cases with initially “large” UM sizes. Decrease in the signs of intratumoral vascularization of UM was noted from the first month of follow-up and this tendency was maintained throughout the whole period.

Conclusions. The presented preliminary results of hybrid PDT in combined treatment of UM expand the possibilities of organ-preserving treatment of largesized tumors due to direct cytotoxic and antiangiogenic effects on tumor substrate, as well as potentiation of radiation therapy.
