REFLETINDO SOBRE AS CIDADES BRASILEIRAS COMO CONSTRUCTOS MASCULINOS
Authors: Rodrigues Walace , Pontes Borges Thelma
Published: September 2023

Este artigo traz reflexões sobre as cidades brasileiras a partir de uma visão de gênero e demonstra que os espaços públicos se materializam como arquiteturas do abandono por não acolher o público feminino, as crianças; enfim, todos que não sejam homens heterossexuais. Nossa pesquisa para este texto foi qualitativa e de cunho bibliográfico. Autores importantes para este escrito são: Barbosa (1995), Butler (2020), Santos (1996), Harvey (2000), Gehl (2015), Freitag (2006), Maricato (2013), Kern (2021), entre outros. Como resultado, compreendemos as cidades brasileiras como constructos eminentemente masculino, pois aqueles que projetam as cidades são, historicamente e em sua grande maioria, homens. Tal planejamento deixa de lado necessidades básicas femininas, como banheiros públicos, trocadores para bebês, calçadas acessíveis, entre outras condições urbanas e espaços majoritariamente de uso feminino. Vemos a necessidade de adequação dos espaços públicos para o acolhimento das pessoas e a diminuição das desigualdades de acesso a estes espaços.

Published: September 2023

A atividade da pesca artesanal desenvolvida pelas comunidades localizadas no Complexo Lagunar Bonfim-Guaraíra, é a principal forma de trabalho e renda, além de ter uma grande importância cultural. Parte-se do pressuposto que o espaço social da lagoa não é apenas material e paisagístico, existem significados sociais intrínsecos ao modo de vida dos pescadores e marisqueiras. O objetivo deste artigo é dialogar com as teorias sobre tempo, espaço e cultura, para tentar compreender como os interlocutores constroem e reconstroem o espaço em que vivem e de que forma isso está relacionado com a cultura local. A partir da análise dialética entre as teorias e as notas do diário de campo (pesquisa piloto empírica, realizada entre os meses de janeiro/2014 a agosto/2014), pretende-se apreender os significados sociais e culturais da Lagoa de Guaraíra. Por fim, depreendeu-se que os diálogos teóricos sobre tempo, espaço e cultura foram vivenciados e correlacionados aos diálogos empíricos, a partir dos discursos sobre a construção do espaço da lagoa e dos significados socioculturais inerentes às atividades de pesca, mariscagem e lazer no estuário.

In present work, the magneto-electronic and optical features of Sr1-xNixTiO3 (x = 12.5%, 25%, 50% and 75%) compounds are calculated using full potential linearized augmented plane wave (FP-LAPW) scheme within density functional theory (DFT) as employed in WIEN2k software. The electronic band structures (BS) and density of states (DOS) interpret the induced half metallic ferromagnetism mainly originating from highly spin polarized Ni-d states. The computed value of total magnetic moment of Sr1-xNixTiO3 is 1.99998, 1.99991, 2.00003 and 2.00005 µB at 12.5%, 25%, 50% and 75% concentration respectively, which emerge primarily due to Ni-3d electrons. Furthermore, the optical features (refraction, dielectric function, absorption, and reflectivity) have also been computed within energy range of 0-10 eV. Sr1-xNixTiO3 is optically active in visible to ultraviolet (UV) region owing to low reflectivity and high absorption. Results portray that the studied compound is a potential contender for its usage in the development of spintronic and optoelectronic devices.

Published: September 2023

For a short period during early development of mammalian embryos, both X chromosomes in females are active, before dosage compensation is ensured through X‐chromosome inactivation. In female mouse embryonic stem cells (mESCs), which carry two active X chromosomes, increased X‐dosage affects cell signaling and impairs differentiation. The underlying mechanisms, however, remain poorly understood. To dissect X‐dosage effects on the signaling network in mESCs, we combine systematic perturbation experiments with mathematical modeling. We quantify the response to a variety of inhibitors and growth factors for cells with one (XO) or two X chromosomes (XX). We then build models of the signaling networks in XX and XO cells through a semi‐quantitative modeling approach based on modular response analysis. We identify a novel negative feedback in the PI3K/AKT pathway through GSK3. Moreover, the presence of a single active X makes mESCs more sensitive to the differentiation‐promoting Activin A signal and leads to a stronger RAF1‐mediated negative feedback in the FGF‐triggered MAPK pathway. The differential response to these differentiation‐promoting pathways can explain the impaired differentiation propensity of female mESCs.

Authors: Romero-Mora María Monserrat , Meza-Picado Victor Hugo , Barrantes-Rodríguez Alfonso , De Camino-Velozo Ronnie
Published: September 2023

[Introducción]: El cultivo de madera sostenible pierde terreno ante la producción agrícola y otros usos de la tierra; para contrarrestar esto, es necesario entender como el productor toma decisiones. Con esto, diseñar esquemas de manejo que se ajusten a la forma de gestionar la finca. [Objetivo]: Identificar los factores que influyen en el proceso de toma de decisiones de los pequeños productores que deben ser considerados para la promoción del cultivo de madera. [Metodología]: Se aplicaron encuestas con preguntas abiertas y selección única al 100 % de los productores (N= 77) de dos asentamientos del INDER. Por la complejidad de las interacciones entre factores, se simplifico el análisis en tres enfoques. Los datos se graficaron a partir de un modelo de regresión local (LOESS), en el cual la curva de regresión se genera y suaviza con el uso de la función geom_smooth del lenguaje estadístico R. [Resultados]: Se identificaron un total de 162 interacciones entre factores Indirectos y Directos. Los productores se clasificaron entre tres grupos, según las veces que cambio de sistema de producción en periodos cortos (5 años). El Grupo A, tiene una mayor representación en la población con un 67.5 %, le sigue el Grupo B con un 24.7 % y el Grupo C con un 7.8 %. El 67.5 % de los productores no se encontraban de acuerdo en incluir el cultivo de madera. [Conclusiones]: Se logró demostrar la existencia de factores de decisión que influyen en la forma de como el productor adopta los sistemas agrícola contrarios al esquema actual de cultivo de madera. La venta segura (VS) es uno de ellos; por consiguiente, los esquemas de manejo forestal actual deben ajustarse al comportamiento de adopción de los sistemas agrícolas y a la lógica de gestión de la finca.

Published: September 2023

3,4-Dimethylpyrazole phosphate (DMPP) is acknowledged as one of the most efficient nitrification inhibitors (NIs); however, researchers have suggested that its effectiveness needs to be further improved. The authors combined the biostimulant seaweed extract (SE) with DMPP and conducted an indoor incubation experiment to initially investigate the impact of the influence of SE on the degradation and effectiveness of DMPP. Meanwhile, a method for the extraction and determination of DMPP was developed. DMPP performed better, with a longer effective time in loess than black soil, and SE showed a delayed effect on DMPP degradation of DMPP at the beginning of the incubation and then accelerated the degradation process. This was attributed to the adsorption effect of SE on DMPP, consequently reducing its effectiveness. The SE delayed the hydrolysis of urea in various soils; however, no significant impact on urease activity was observed (P < 0.05) (P < 0.05). Furthermore, it also increased potential nitrification rate (PNR) from 10 to 21 days and promoting the rapid transformation of NH4+-N in black soil. The SE reduced PNR within 21 days and inhibited nitrification in loess. In addition, the SE appeared to mitigate the adverse effects of excessive nitrogen on microorganisms The combination of DMPP and SE was not conducive to the inhibition of soil nitrification, and this formulation in field applications requires further investigation.

Published: September 2023

Seamless integration of the body and electronics toward the understanding, quantification, and control of disease states remains one of the grand scientific challenges of this era. As such, research efforts have been dedicated to developing bioelectronic devices for chemical, mechanical, and electrical sensing, and cellular and tissue functionality modulation. The technologies developed to achieve these capabilities cross a wide range of materials and scale (and dimensionality), e.g., from micrometer to centimeters (from 2-dimensional (2D) to 3-dimensional (3D) assemblies). The integration into multimodal systems which allow greater insight and control into intrinsically multifaceted biological systems requires careful design and selection. This snapshot review will highlight the state-of-the-art in cellular recording and modulation as well as the material considerations for the design and manufacturing of devices integrating their capabilities.

Lärares relationskompetens i växelspelet mellan ’Mig’ och ’Jag’
Authors: Aspelin Jonas
Published: September 2023

I skandinavisk utbildningsforskning används ofta begreppet relationskompetens för att beskriva lärares förmåga att initiera och upprätthålla goda relationer. Bland annat har man undersökt hur lärarstudenters relationskompetens kan utvecklas. Fältet karakteriseras mestadels av empirisk forskning och det har framförts behov av fler teoretiska studier. Föreliggande artikel har två syften. Det första är att diskutera begreppet lärares relationskompetens med stöd i George H. Meads begrepp ’Mig’ och ’Jag’. Det andra syftet är att, med utgångspunkt från begreppsdiskussionen, diskutera resultat från tre interventionsstudier av lärarstudenters uppfattningar om relationskompetens och, mer specifikt, hur studenternas utveckling i de aktuella projekten kan förstås. I den första diskussionen förstås relationskompetens utifrån fyra perspektiv, som: (i) konkret rollövertagande; (ii) abstrakt roll-övertagande; (iii) direkt respons och (iv) växelspel mellan ’Mig’ och ’Jag’. I den andra diskussionen indikeras att lärarstudenternas uppfattningar utvecklas genom skiften från de första tre perspektiven till det fjärde perspektivet. Det fjärde perspektivet skrivs alltså fram som ett slags syntes; lärares relationskompetens förstås huvudsakligen som realiserad i en snabb, eller hypersnabb pendling mellan ’Mig’ och ’Jag’, socialitet och individualitet. Avslutningsvis kommenteras syntesens teoretiska och praktisk-pedagogiska implikationer.
Att höra till eller inte? Föränderliga kapital, positioneringar och tillhörigheter från grundskola till högskola
Authors: Eliaso Magnusson Josefina , Bergnehr Disa
Published: September 2023

Denna studie undersöker en tonåring och sedermera ung kvinnas tal om att i olika skolsammanhang positioneras och positionera sig själv som avvikande, ’den Andre’, den ’invandrade’, i relation till majoritetsgruppen, ’det svenska’. Mer specifikt analyseras hur olika kapital och positioneringar förändras och får olika innebörd över tid, från grundskola till högskola. Studien bygger på longitudinella etnografiska data som samlades in genom fältarbete. Här analyseras intervjuer, samtal och fältanteckningar som genomfördes med studiedeltagaren vid två nedslag, under skolgången i årskurs 9 och under tiden som högskolestudent, med hjälp av begreppen kapital och hybriditet. Studien belyser hur tillhörighet och utanförskap kan förstås och få mening på olika sätt under olika perioder i livet, och är kopplade till olika sammanhang. Studiedeltagaren förstår och motiverar sina val och handlanden genom att positionera sig själv och andra som den/de som tillhör alternativt inte tillhör, men i delar präglas denna positionering av hybriditet och motsägelsefullhet.

Features of the functioning of the compliance control system in agriculture
Authors: Babukin Georgy , Botasheva Lyudmila
Published: September 2023

The paper presents the results of the analysis of the characteristics of the use of compliance control in the practice of agricultural enterprises. The relevance of the study on the selected issue is due to the fact that compliance control forms a systemic focus of management processes within an agricultural organization that ensures effective risk management, economic security and sustainability. Within the framework of the article, the theoretical aspects of the concept of "compliance control" are considered. The interaction of compliance control with compliance with antimonopoly regulation legislation is analyzed. The role of the internal control mechanism of an agricultural enterprise in compliance control is determined. The main methods and tools of the risk management system, which ensures the achievement of the goals of compliance control of an agricultural organization, are considered.
The risk management system in an agricultural organization promotes the application of measures and solutions that reduce the negative impact of the risks of the internal environment and threats to the external environment. This is carried out using the mechanism of early detection of factors leading to risks and threats to the enterprise. The controlling procedure in monitoring the effectiveness of the financial and production activities of an agricultural organization ensures the functioning of the accounting system and economic security.
The authors come to the conclusion that an effective solution for organizing an effective risk management system in an agricultural enterprise is an unconditional combination of various methods. Each of them is used for certain types and forms of business threats. With regard to the general mechanism of compliance control, its use in the practice of agricultural organizations of the Russian economy is due to the need to comply with various regulations, obligations and rules on which the economic security and efficiency of commercial activities depend. In the current conditions of instability, compliance control is gaining great practical value and popularity among agricultural enterprises.
Resources and regulation of resource conservation at various stages of the object's life cycle
Authors: Mangushev Ilgiz , Politi Violetta
Published: September 2023

The relevance of research. At present, the system of regulation of economic activity in Russia belongs to the mobilization type. Among the economic tasks of the mobilization period, one can single out the task of building new external and internal economic contours of the interaction between production, consumption and investment. Among the new economic phenomena of the current period, it should be noted the growing role of resource conservation in the context of maximizing the involvement of internal reserves in the economic turnover.
Sustainable and at the same time progressive development of an enterprise of any form of ownership and type of economic activity is associated with effective decisions on the use of resources. In general, the strategic and current management of enterprise resources is the area of competence of the quality management system, one of the functions of which is resource management. An integral element of a comprehensive quality institution is standardization as an open, dynamic and adaptive system.
On the territory of the Russian Federation, the problem of resource saving in the construction process is of particular relevance, since most of the country's territory is located in areas with a harsh climate, which requires an increased volume of resource consumption, in particular, those related to the thermal protection of objects.
The purpose of the work is to identify the essence of the concepts of "resources" and "resource saving" and to summarize recommendations for organizing the handling of biosphere and technosphere resources in the "design-construction-operation" system.
The object of the study is the national standards of the Russian Federation, federal laws and by-laws that regulate the process of resource saving at all stages of the creation of construction products.
The subject of the study is design and construction activities carried out according to the criteria of energy saving and material saving in accordance with the environmental policy and guidelines.
Research result. The authors present a classification of national resources in the concept of resource saving. The potential resources of enterprises as part of the external and internal circuits are considered as the basis for the study of resource saving. The authors of the article also developed a Matrix of standards governing resource saving at the stages of the life cycle of the creation and operation of an industrial/residential facility
Systematization of supply chain problems due to the imposition of sanctions that impede sustainable development
Authors: Bykova Galina , Wende Frank-Detlef
Published: September 2023

The authors of the scientific publication explore the supply chain problems that arose as a result of the imposition of sanctions. According to business reports, logistics in our country has been hit, and it has found itself in a crisis situation, with all types of transportation affected. The logistical problems, which have worsened with the imposition of sanctions, have been most pronounced in international supply chains. Regardless of the localization of the supply chain, the imposition of sanctions by Western countries affected the international transportation of material flow. Therefore, the problems that have arisen have led to the need for a significant transformation of supply chains in our country, both in terms of export and import material flows. The systematization of supply chain problems due to the introduction of sanctions that impede sustainable development allowed the authors of a scientific article to divide them globally into two typical sets. The identified problems that arose as a result of the imposition of sanctions were systematized by the authors of the scientific article in chronological order. This makes it possible to better assess the very fact of the immediacy of their occurrence at the beginning of the period of imposition of sanctions and the corresponding complexity of their solution. Such problems were distinguished by the fact that they required considerable time and effort to solve them, including from state regulatory bodies, including the need for a quick response to develop and implement appropriate changes in regulatory legal acts. The analysis performed showed that as we moved through the hierarchical set of problems, both business and state regulatory authorities related directly or indirectly to the transport sector were able to respond more quickly to emerging problems as sanctions were tightened, since certain experience had already been gained
External public debt of the Russian Federation: risk assessment and improvement of the management system
Authors: Mirgorodskaya Marina , Kapustina Nadezhda , Anichkina Olga , Apachanov Anton , Ikonnikova Anzhela
Published: September 2023

This scientific article deals with issues related to risks arising from external public debt. The authors of the article note that the state's own resources and funds do not always allow satisfying the country's unlimited needs, so borrowing from abroad becomes necessary. One of the reasons why states are forced to resort to external borrowing is the problems associated with financing budget expenditures. In today's realities, it is very important to rationally approach the issue of managing external debt, because its cancellation can seriously affect the future stability and ensure the country's national economic security. The growth of the external debt of the state, according to the authors, can lead to an increase in tax rates, diversion of funds, economic recession, inequality between people, as well as the transfer of debt to subsequent generations. Consequently, the external debt management policy is designed to enable the state to attract funds from other sources, solve social problems and ensure economic security. According to the authors, external debt is an essential link in the macroeconomic system of any country, because it affects public finances, the investment climate, money circulation and international cooperation. Those relationships that develop during the formation and repayment of debt can significantly affect the long-term economic potential of the country. In this regard, the authors note that it is necessary to conduct a comprehensive policy of the state in relation to external debt and balance its income and expenses so that there is no need for borrowing from abroad, and so that a situation does not arise in which external debt becomes the most serious obstacle to difficult path of economic transformation.
The relationship of economic security and competitiveness of the enterprise in modern conditions
Authors: Kvasov Andrey , Akhmetov Minnegaley
Published: September 2023

The author of a scientific publication examines the justification of the impact of economic security on the competitiveness of an enterprise. In modern conditions, when the economic situation in the world is constantly changing, and competition in the market is becoming increasingly fierce, it becomes essential for enterprises to have several key success factors. According to the author, one of these factors is competitiveness, which includes the ability of an enterprise to meet the needs of its customers and offer quality goods and services at an affordable price. The author notes that competitiveness is one of the main factors that allows an enterprise to retain its customers, attract new ones and increase its market share. To be highly competitive, an enterprise must have a strong brand, create a unique experience for its customers, an effective marketing and management strategy, and a professional and motivated workforce. However, as the author noted, competitiveness is not the only factor determining the success of an enterprise. An important aspect is economic security, which is aimed at reducing risks and protecting the financial structure of the enterprise. Ensuring economic security allows the company to successfully compete in the market, take risks and invest in the development of its activities. In addition, it is important to pay attention to the quality of products and services, their value for money, management efficiency, as well as attention to customer needs. The company must pay special attention to product quality in order to retain its customers and attract new ones. It must also set reasonable prices for its products and services in accordance with their quality. Summing up the study, the author mentions that in order to succeed in the market, an enterprise must have a set of key factors, including competitiveness, economic security, product and service quality, management efficiency, attention to customer needs, the use of modern technologies and social responsibility. Only in this way will the company be able to succeed in the current economic situation and take a leading position in the market.

Para tal, foram realizadas 12 coletas na área ao longo do ano de 2019. 220 species were recorded, belonging to 154 genera and 62 families. The most representative families in this area were Fabaceae (38 spp.), Rubiaceae (15 spp.) and Myrtaceae (nine spp.). The predominant habit were herbs and shrubs. The richest fragment was the Cerrado with 171 species, with the Typical Cerrado (104 spp.) phytophysiognomy being the most representative. Of the total species, most are native, 16 are new records for Ceará, 12 are endemic to the Caatinga domain and seven are endemic to the Cerrado. Thus, the present site presents a high heterogeneity of species, in addition to varied habits, new records and endemic species of Cerrado and Caatinga.
O “ENTULHO AUTORITÁRIO” E O DISCURSO “CONSERVADOR” NO BRASIL
Authors: Bachini Natasha , Arruda Pedro Fassoni
Published: September 2023

Neste artigo, analisamos as ressonâncias entre o entulho autoritário presente nas instituições e o discurso “conservador” contemporâneo. Entendemos que a ausência de uma justiça de transição, combinada à manutenção dos poderes e privilégios das Forças Armadas na Carta de 1988, respalda tanto a atuação desses atores no passado, quanto práticas autoritárias por parte das instituições e entre os próprios cidadãos no presente. Mediante as oportunidades políticas surgidas no último decênio para a direita, observa-se a recuperação e atualização de argumentos muito frequentes naquele período como os da tutela militar, da ameaça comunista e da rejeição aos direitos humanos, que vêm sendo difundidos, sobretudo, pelas mídias sociais.
Comparative Assessment of Catalase Levels in Peri-Implant Health and Disease
Authors: Rithanya M. , Rajasekar Arvina
Published: September 2023

Peri-implant disease pathogenesis is similar to periodontal disease pathogenesis resulting in production of pro-inflammatory mediators. These mediators alter the redox balance leading to decrease in antioxidants, among which catalase is one of the enzymatic antioxidants. The aim of the study was to compare the levels of catalase in peri-implant health and disease. The present observational study was carried out from June 2022 to December 2022 in the Department of Implantology, Saveetha Dental College and Hospitals, Chennai, India. A total of 60 patients with peri-implant health (Group 1; n = 20), peri-implant mucositis (Group 2; n = 20) and peri-implantitis (Group 3; n = 20) were enrolled. Unstimulated salivary samples were collected and subjected to ELISA for catalase analysis. Catalase levels were then compared between the groups using ANOVA. The mean catalase level in peri-implant health, peri-implant mucositis, peri-implanti-tis were 25.07 ± 0.44 U/mL, 18.5 6 ± 0.65 U/mL, and 11.25 ± 0.76 U/mL respectively. The difference between the three groups were statistically significant (P < 0.05). Catalase level decreases with severity of peri-implant diseases. Therefore, catalase can be used as a diagnostic marker for peri-implant diseases.

Sports tourism as a new form of tourist activity – terminology and history of the concept
Authors: Łuć Bartłomiej
Published: September 2023

This article deals with the broadly understood concept of sports tourism. Although this term has been used for a relatively long time, it was not until the 1970s that research on the concept and all kinds of considerations began. The complex nature of the phenomenon and the research being carried out all the time result in many doubts regarding this concept. The development of research and reflection on this concept is becoming more and more apparent every year. The increase in the number of publications relating directly to this topic is also strongly noticeable. In this article, an attempt has been made to order and systematize scientific publications and research results that have been developed so far. The article has been prepared on the basis of a search and analysis of literature sources related to both sports tourism and the geography of tourism, or concepts related to sport. Both foreign literature and Polish literature sources were taken into account. The aforementioned literature review was presented in a chronological order. The article also mentions the alleged beginnings of the phenomenon of sports tourism dating back to ancient times. The content has been supplemented with the author’s remarks. The review of the literature has proved that the phenomenon of sports tourism has not yet been fully described and researched, which is undoubtedly due to the short time of intensification of research and deliberations on this concept.

Materials and methods. The authors analyzed the treatment outcomes of 1000 recipients who underwent liver transplantation from April 2008 to April 2023. The study involved analysis of correlation between infections associated with health care and main risk factors, including contamination of different loci and preservation solution.

Results. The incidence of healthcare-associated infections accounted for 22.2%. The cumulative incidence of donor organ and recipient contamination was 9.85%. Transmission of infection occurred in 29% of cases. Sepsis developed in 8% of all recipients with healthcare-associated infection. The mortality rate was 70% in cases of sepsis. After liver transplantation, in-hospital mortality was 9.3%. Urgent transplantation was required in 10.7% of observations. Univariate regression analysis shows the highest risk contribution to healthcare-associated infection for the MELD score, contamination of preservation solution with multidrug-resistant flora, severe early graft dysfunction, blood loss, and warm ischemia time.

Conclusion. Contamination of preservation solution increases the risk of bacterial complications associated with liver transplantation. The resistance profile affects the development time, structure and outcome of these complications. Timely diagnosis and infection control measures are fundamental to preventing the infectious complications.

The paper presents the evolution of views on the surgery of portal hypertension, as well as some historical aspects of its development. The authors considered the main types of surgical interventions to be performed in this pathology.        It is noted that in the middle of the 20th century, the direct portacaval anastomosis gained the widest acceptance of   all the proposed types of vascular anastomoses. A number of surgeons considered it a classical method of treatment in portal hypertension. Thereafter, the indirect portacaval anastomosis proved to have the best outcomes. The advantage of portacaval anastomoses in comparison with other modifications of surgeries was substantiated by a significant decrease in portal pressure and disappearance of oesophageal varices after developing the anastomosis. Surgical treatment of patients with liver cirrhosis and portal system thrombosis reasonably requires closer attention of doctors in various fields. Such patients should be managed in specialized clinics and well-equipped medical centers.

Aim. To study the influence of infectious complications on the outcomes of orthotopic liver transplantation.

Materials and methods. The methodology involved analyzing the outcomes of 159 orthotopic transplantations of full postmortem liver for 2013–2022. Surgical complications were classified according to Clavien-Dindo (2004). Special attention was paid to microbiological examination of biological fluids with determination of the pathogen species and susceptibility to antimicrobial agents. Determination of isolated cultures and sensitivity to antibacterial agents was carried out using automatic analyzers. Sensitivity and resistance to antimicrobials were determined according to the recommendations of the European Committee (EUCAST, www.eucast.org).

Results. At present, 78 of 141 recipients are alive. After discharge, 42 died of various causes within 4–124 months. In-hospital mortality was 9.9% after primary liver transplantations and 38.9% after retransplantations. Recently, K. pneumoniae (18.8%), E. coli (18.7%), C. albicans (9.7%) have dominated the pathogen spectrum. In microbiological examination, after primary transplantation, pathogens were more often isolated from the wound discharge, after retransplantation – from the biliary system.

Conclusion. Infectious complications remain a significant cause of unsatisfactory outcomes of liver transplantation. The greatest negative prognostic role belongs to biliary infection caused by multidrug-resistant pathogens in combination with insufficient arterial blood supply of the transplant.

Aim. To evaluate the immediate and long-term results of two-stage liver resection performed by means of ALPPS technique.

Materials and methods. The retrospective analysis involved 7 patients (mean age 62 years) with intact liver parenchyma volume (Future Liver Remnant, FLR) <25%. All patients underwent ALPPS from 2014 to 2021. Both stages of ALPPS were performed in the traditional way. The increment of intact parenchyma on days 6–8 after stage I was evaluated by CT volumetry. The main operative characteristics, incidence of postoperative complications according to Clavien-Dindo and ISGLS, time without progression and life expectancy were analyzed.

Results. The median duration of ALPPS stage I was 250 min, median blood loss was 600 ml, and stage II – 210 min and 300 ml, correspondingly. The median FLR before and after ALPPS stage I was 15.3% and 31.6%. The median FLR hypertrophy after ALPPS stage I accounted for 123%. The median interval between stage I and II of ALPPS was 10 days. All patients underwent R0 resection. The incidence of postoperative complications after ALPPS stage I was 14.3% (Clavien–Dindo I), after stage II – 57.1% (Clavien–Dindo III–V). The mortality rate within 90 days after ALPPS stage II accounted for 14.3%. Median follow-up was 25 months. The median time without progression in 6 patients operated for colorectal cancer metastases was 6 months, the median life expectancy was 31 months. The patient who underwent ALPPS for hepatocellular carcinoma is alive, no signs of disease progression have been detected.

Conclusion. ALPPS provides a rapid and more than two-fold growth in FLR and increases the likelihood of R0 resection in patients with initially unresectable primary and secondary liver tumors. However, the immediate results of ALPPS are unsatisfactory. The indications for surgery are extremely controversial due to the development of drug therapies, ablation techniques and radiotherapy.

Aim. To study the reasons for stone migration from the gallbladder into the main bile ducts after endoscopic lithoextraction and to develop methods for preventing recurrent mechanical jaundice before performing the cholecystectomy.

Material and methods. Delayed cholecystectomy was recommended for 328 patients with calculous cholecystitis and mechanical jaundice after endoscopic papillosphincterotomy, lithoextraction and restoration of adequate bile outflow. 23 patients were readmitted to hospital with recurrent mechanical jaundice caused by recurrent choledocholithiasis. All patients underwent duodenoscopy, endoscopic retrograde cholangiography and lithoextraction within 12 hours after admission. The size of the gallstones, the diameter of the cystic duct, the level of its insertion into the common hepatic duct, and the length of the previously performed papillotomy were considered as possible causes of recurrent choledocholithiasis.

Results. Multiple gallstones of 2–4 mm and low cystic duct insertion into the common hepatic duct were detected in all 23 patients. An increase in the diameter of the cystic duct >5 mm was revealed in 18 patients. In 10 patients, the initial papillotomy was <8 mm.

Conclusion. The factors predisposing to recurrent mechanical jaundice due to migration of gallstones into the bile duct and indications for its stenting after lithoextraction before cholecystectomy are ultrasound signs of multiple small gallstones, low insertion the dilated cystic duct into the bile duct, and partial, non-extended papillotomy.

Aim. To evaluate different therapeutic and diagnostic approaches in spontaneous bile duct perforation.

Materials and methods. The present study involved the reports on spontaneous perforations in the bile duct system, published from 01.01.2000 to 01.06.2022 and selected by structured search in PubMed/Medline database.

Results. As a result, 58 articles describing 71 patients were selected for the study. The most frequent symptoms of the disease included abdominal pain (92.9%), fever (39.4%), and jaundice (33%). The provisional diagnosis was made correctly in 52.1% of cases. The development of the disease was most often associated with choledocholithiasis (38%). Bile ducts perforation of the left hepatic lobe was revealed in 40.6% of cases, perforation of the common bile duct – in 35.5%. Bile duct perforation resulted in peritonitis in 42.2% of patients and bile accumulation or abscess in 30.9%. Encapsulated and intrahepatic accumulation of bile was found in 18.3% of cases. Management of perforations with development of encapsulated and intrahepatic bile accumulation included combined treatment, embracing percutaneous transhepatic drainage and endoscopic methods. Perforation of bile ducts with development of extensive forms of the disease required two-stage treatment. The first stage involved lavage of the abdominal cavity and decompression of the biliary tract. The second stage involved resective and reconstructive surgery to eliminate the cause of the perforation. The mortality rate was 5.6%.

Conclusion. Spontaneous perforation in the bile duct system is a rare pathological state appeared as a complication of hepatopancreaticoduodenal diseases. Its management requires greater awareness of abdominal surgeons. The surgical strategy is based on correctly diagnosed and staged treatment tactics, which allows the incidence of complications and mortality rate to be reduced.
