Introducción: El síndrome de hueso hambriento (SHH) es una complicación asociada a la realización de una paratiroidectomía, definido por la persistencia de más de 4 días de hipocalcemia (Calcio sérico menor a 8,5 mg/dl) con requerimiento de suplementación de calcio endovenosa. Este es el primer estudio realizado en Colombia, que tiene el objetivo de precisar la prevalencia de SHH en un Hospital de referencia en Latinoamérica. Metodología: Se realizó un estudio de corte transversal retrospectivo; se revisaron los registros de historias clínicas de pacientes con antecedente de hiperparatiroidismo primario, secundario y terciario que requirieron paratiroidectomía parcial o total en el Hospital de San José de Bogotá, entre Enero del 2013 y Diciembre de 2021. Resultados: Se identificaron 247 pacientes con diagnóstico de hiperparatiroidismo, la mayoría de los pacientes (65.1%) fueron hombres, con una edad media de 50.9 años (rango de 25 a 71 años). La prevalencia del SHH fue del 11.7%, con una relación mujer-hombre de 1.5:1, no hubo casos de patología maligna. Los niveles de hormona paratiroidea séricos preoperatorios tuvieron una correlación estadísticamente significativa con los niveles de hormona paratiroidea postquirúrgica. Conclusiones: El síndrome de hueso hambriento es una complicación que puede presentarse posterior a la realización de una paraitroidectomia. Este estudio presenta una prevalencia más baja que la descrita en la literatura

La disfagia alta es un síntoma frecuente de consulta al otorrinolaringólogo o gastroenterólogo. Los diagnósticos diferenciales son trastornos de la deglución por daño neurológico, anillos esofágicos superiores, globus faríngeo, neoplasia, disfagia lusoria y trastornos motores inespecífico y otras más raras aún. Hay escasa literatura actualizada en pacientes adultos. El diagnóstico se basa en el estudio radiológico baritado, endoscopia y complementariamente con manometría. Las opciones de tratamiento son motivo de discusión, dada la poca evidencia disponible. En este artículo se presentan los resultados observados en una cohorte de 10 pacientes con diagnóstico confirmado de acalasia del cricofaríngeo sometidos a dilatación endoscópica (7 pacientes) o miotomía quirúrgica por cervicotomía (3 pacientes). Se evaluó evolución de la disfagia, complicaciones post procedimiento y resultados a largo plazo. No hubo complicaciones mayores, la disfagia mejoro en ambos grupos, en el grupo de dilatación se complementó el tratamiento con dilataciones periódicas en 2 pacientes. No hubo diferencias significativas en los 2 grupos estudiados.Conclusión: ambas opciones terapéuticas presentan buenos resultados en el tratamiento de estos pacientes.

Mycobacterium tuberculosis causes Tuberculosis (TB), an infectious disease. The study aims to evaluate DOTS therapy's impact on pulmonary TB and TB-HIV patients. This research used a descriptive qualitative study design with a retrospective descriptive research approach using secondary data for the period June 2017 to July 2020. The analysis uses the Miles and Huberman model. A study of 305 people found that 83% of pulmonary TB cases completed treatment within the initial phase, 64% completed the continuation phase. TB-HIV cases 93% completed treatment within the initial phase, 71% the continuation phase. The combination of OAT and ARV doses was successful in reducing initial smear conversion in pulmonary TB cases. The treatment was evaluated as cure in pulmonary TB cases, complete in pulmonary TB-HIV cases, and had no treatment failure status in both groups. Treatment success in pulmonary TB patients was not significantly related (p-value≥5%) with the type of OAT, type of PMO, gender, and age. Whereas in HIV co-infected pulmonary TB patients, treatment success was significantly related (p-value <5%) with the type of PMO, and not related (p-value≥5%) with the type of OAT, gender, and age.

Aim. To perform an assessment of the performance of investments in business acquisitions over the years to 2021 by analyzing the impairments recognized in 2021 and 2022.Objectives. To examine the possible approaches to analyze the performance of mergers and acquisitions; to elaborate on one of the approaches in the aspect of investigating the impairment of goodwill previously recognized as a result of company acquisitions; to analyze the indicators of available financial statements of companies for 2021 and 2022.Methods. The study is based on the analysis of consolidated financial statements of Russian companies and sample data on foreign companies. We considered individual transactions on foreign companies’ exit from the Russian market and assessed the effect of their influence on the financial statements of foreign companies.Results. The authors have carried out a post facto evaluation of the indicators of the largest Russian companies in the sample, assessed the possibilities of goodwill recovery as a result of M&A transactions. As a result of the analysis the conclusion is formed that the situation in the considered sector of economy remains stable. Meanwhile, foreign investors who have left the Russian market recognize significant impairment of investments in their financial statements.Conclusions. The prospect for further research is to conduct a more extensive analysis based on a larger sample of companies. In 2023, some companies that preferred not to publish their 2022 financial statements have started to disclose their financial results again. This provides an opportunity to continue the research begun in the paper on the results obtained and to make further refinements.

Aim. To assess the state of the scientific potential of the Magadan Oblast from the point of view of its influence on the formation of economic security of the region.Objectives. To define the concept of “scientific potential of the region” and reveal its structure; to consider the existing approaches to assessing the scientific potential of the region; to conduct a comparative analysis of the scientific potential of the Magadan Oblast and the Far Eastern Federal District (FEFD).Methods. The scientific potential of the region is considered in the plane and component aspects from the position of three components: technological, innovative, educational. The assessment of each component is based on three interrelated planes: formation, development and utilization.Results. The tendency to decrease the scientific potential of the Magadan Oblast in all three components both in absolute terms and in comparison with the indicators of the Far Eastern Federal District has been revealed. The greatest reduction of indicators is revealed in the sphere of scientific and technological potential.Conclusions. There is a growing threat to the economic security of the region due to the lag of the Magadan Oblast from other regions of the Far Eastern Federal District both on the level of innovation and technological development and on the formation of scientific personnel for the needs of the regional economy. It is recommended to concentrate efforts in the sphere of development of scientific and educational potential, since it is the sphere that determines the strategic development of the region and long-term economic security.

Aim. To identify trends and directions of development of ESG-agenda of the Russian banking sector in the new geopolitical environment.Objectives. To analyze the reaction of the Russian banking sector to the promotion of ESGagenda by the West in the pre-sanctions period and the change of priorities after the introduction of large-scale financial and technological sanctions for Russia; to determine the required transformation of business strategies and risk management systems; to propose additional measures of support from the state to increase the priority of sovereign technologies in the implementation of ESG-transformation and the development of a competitive national system of standards.Methods. The authors applied a mixed method of analysis, combining qualitative and quantitative data, to form the empirical base of the study. Content analysis and empirical methods were used to analyze qualitative data. In turn, quantitative data were processed using statistical and logical tools.Results. The conducted research allowed to confirm the effectiveness of ESG-tool in the realization of the concept of sustainable development. It was determined that the significant driving force of ESG-transformation today is mainly large banks. However, the potential of ESG-transformation on the part of banks may be exhausted, and the practical part of fulfillment of plans reflected in their ESG-policies requires additional incentives from the state.Conclusions. Based on the results of the conducted research, it becomes clear that it is necessary to form a competitive Russian sovereign ESG-model, which should include a national regulatory framework, technological standards, and domestic platform IT management systems. Strengthening the work in this direction’ financial market participants are most able to influence the introduction of innovations in the sphere of tools for achieving sustainable development goals (SDGs) and national projects, to take into account national interests in view of ESG-agenda realization, to ensure their development and financing.

Published: November 2023

This study assessed the barriers to strategy implementation on the performance of Kenya Power and Lighting Company Limited (KPLC) in Nairobi County, Kenya. It had four objectives: to establish the influence of strategic leadership, staff competencies, strategic planning, and organizational structure on performance of KPLC. The study used a descriptive research design. The study was conducted at Kenya Power and Lighting Company. The managerial employees of Kenya power and Lighting Company Limited constituted the study's population. At Kenya Power and Lighting Company Limited, there were 180 management staff members who made up the sample frame for the research. Formulae developed by Yamane (1967) were used to determine how representative the survey's sample was of the whole population. Sample size was 124 respondents. A questionnaire was used to collect data from respondents who are randomly selected from different departments or units of KPLC. The data was analyzed using SPSS version 21 and presented using descriptive statistics. Descriptive and inferential statistics were obtained. The study found that all the four objectives revealed a positive influence on performance of KPLC. In conclusion, strategic leadership, staff competencies, strategic planning, and organizational structure play crucial roles in shaping KPLC's performance by providing direction, motivation, innovation, alignment, coordination, adaptation, evaluation, communication, decision-making, and leadership. Finally, the study recommended that KPLC should continue to foster a culture of strategy implementation that can enhance its performance in a dynamic environment. Moreover, KPLC should also address any potential barriers or challenges in the strategy implementation process or outcomes that may affect its performance or competitiveness

The aim of this work is characteristic of spatio-temporal variability of Pacific water distribution in the Sea of Okhotsk based on Lagrangian approach and spatial analysis.Materials and methods. The study is based on geostrophic current data product from satellite altimetry. The dataset has resolution of 0,25° × 0,25° × 1 day. This data is used for calculation of approximately 100000 water parcels trajectories during 400 days back in time for every day from 31st of January 1997 to 17th of April 2022. For each date in this interval, those parcels which intersected the conditional Kuril transect were determined, as well as region and date of transect intersection. Those two parameters were used in cluster analysis with DBSCAN method in order to distinguish individual Pacific intrusions. Position, shape, and size of each intrusion were investigated.Results allowed to suggest two types of indexes describing distribution of Pacific-origin water in the Sea of Okhotsk. First, centroid of particles of Pacific origin with residence time between 1 and 6 months is calculated. Variability of centroid position showed northward displacement of Pacific waters in spring-summer and south[1]ward displacement in autumn-winter. Eastward displacement towards Kamchatka coast usually occurs during winters and opposite westward displacement is usual for summers. In 1998, 2003, 2010, 2013, 2017, and 2019 waters of Pacific origin had the most northern location. Second type of indexes is based on location and shape characteristics of Pacific water intrusions. The fractal dimensionality and convexity measure of intrusions are rapidly decreasing after the intrusion reaches its maximum area. Centroids of the most prominent intrusions follow the path along 152–154 °E. Both types of indices showed intensification of Pacific inflow since 2010.Practical value. The time-series of resulted indexes are suggested to be implemented in integrated ecosystem assessments of the eastern Sea of Okhotsk.
Studies of microplastic content in water and commercial fish: from scientific research to large-scale monitoring

Purpose. The article presents proposals for the development of studies of microplastic pollution of waters and biological resources in the Russian fishery areas. Materials and methods. The materials of VNIRO on the quantitative assessment of the MPs content in the Arctic Seas in August-October 2019–2022 and modern research on this problem are summarized. MPs samples were collected on the surface of the seas with a Manta-trawl 335 and processed according to a single method. Results. The conducted studies pick up knowledge gaps regarding the real level of marine MPs pollution of the Arctic region.Novelty. No large-scale localization of MPs was detected in the observation areas, the level of plastic pollution on the surface of the Russian Arctic seas was lower compared to other areas of the World Ocean. We point out the relevance of the assumption that a significant part of MPs fragments and fibers are transported by Atlantic and Pacific currents to the Arctic basin. A sample survey of fish in commercial catches for MPs contamination confirmed the presence of its fragments and fibers in the digestive tract of some individuals (pink salmon, greenlings, herring, sea bass) caught in the North Pacific seas in 2019, 2021 and 2022.Practical significance. The global increase in MPs content in the Northern hemisphere seas, exacerbated by climate change, requires a transition from exploratory scientific observations to regular multidisciplinary study of plastic pollution of biotopes of ecosystems of the Arctic, North Pacific and Atlantic seas. The key points and tasks of monitoring microplastic pollution of waters and biological resources in the Russian fishing areas provide for objective and comparable assessments based on the use of unified methods of collection and processing of samples, as well as an ecosystem approach to prevent environmental risks and ensure food safety.

Authors: Semin A. N. , Truba A. S. 
Published: November 2023

The purpose of the work: to determine the main factors hindering the harmonious development of the domestic pollock market, and taking into account the assessment of the potential, the price of fish products, the demand for pollock, the results of monitoring preferences and other factors, to develop scientifically based proposals for its further development.Materials and methods: official data published by the Federal State Statistics Service, the Association of pollock miners (ADM) were used in the work. Diagnostics and monitoring of results were carried out, determinant and systematic approaches were applied. In some cases, content analysis was used.The results of the study consist in identifying factors of a motivational and demotivation nature that affect pollock market participants. Proposals have been developed to eliminate and mitigate the impact of extreme factors on the market. It has been established that the competitive advantages of the pollock market in Russia can be formed not only through access to cheap sources of raw materials, but also through the improvement of organization and management along the entire chain of movement of products from the place of fish catch to its consumption.The practical significance lies in the possibility of using the results of the study in the development of economic, financial, technical and technological measures, methods and mechanisms aimed at solving the problem of increasing the level of per capita consumption of fish products, indicated in the strategy for the development of the fishery complex until 2030.

The goal of the work: to determine the water structure in the Central part of East Atlantic and to identify the features of the distribution of hydrological, chemical and biological characteristics of the upper layer in the autumn periodMaterials and methods: the data presented in the work were obtained on the 63rd cruise of the R/V «Akademik Ioffe» (September 29, 2022–December 8, 2022). During the expedition, hydrological and chemical (temperature, salinity, pH, dissolved oxygen, phosphates, nitrites, nitrates and silicates) characteristics were measured from the surface to the bottom, as well as biological (number, biomass and species diversity of phytoplankton), taken with chemical samples on depths of 0, 10, 20 and 50 m. Chemical analysis was carried out in the ship’s laboratory, according to certified methods for sea and fresh waters. Phytoplankton samples were thickenedusing a reverse filtration funnel through track (nuclear) membranes and fixed with Lugol’s solution to a final concentration of 5%. To study the species diversity, abundance and biomass of plankton microalgae, samples were processed by direct microscopy of algae in a living and thickened drop (V = 0.01 ml), as well as in a counting chamber (V = 0.5 ml) using an Olympus CX43 light microscope (magnification 10×20, 10×40). Identification of taxonomic groups and species composition of microalgae, calculations of the abundance and biomass of phytoplankton, as well as the Sörensen-Czekanowski floristic similarity coefficient according to the adoption of the methods of the « IBSS RAS» were carried out.The practical significance of the research: assessment of the production stock in a poorly studied region of the Central Eastern Caucasus, identification of mechanisms for influencing production processes, assessment of the variability of the water structure against the background of climate change.
Sex steroid hormones and steroid secretory cells in the gonads of cyclostomes and fish
Authors: Zelennikov О. V. , Mosyagina M. V. 
Published: November 2023

. The purpose of this work is to generalize data on the content of sex steroid hormones in cyclostomes and fish in connection with the different state of the gonads, as well as on the localization and ultrastructural organization of steroid secretory cells (SCs). Method used: generalization of literature data. Novelty: for the first time, data on the development of SC in the gonads of juvenile fish are presented on the scale of a literature review; changes in their localization and functional activity are shown. Results: Most of the data on the steroidogenic function of the gonads in fish were obtained in connection with the study of sex differentiation (inversion) and sexual maturation (spawning). The issues of the synthesis of sex steroid hormones and their molecular structure, blood levels in various states of the gonads, as well as the localization and ultrastructural organization of SCs are considered. It has been noted that SCs appear in the gonads long before sex differentiation and can be present among stromal, granulosa, and theca cells. In cyclostomes and fish — juvenile protogynous hermaphrodites in the gonads of genetic males, SCs do not appear in the membranes around the oocytes of the previtellogenesis period, which determines their deficiency of estrogen hormones and, as a result, sex inversion. With induced sex reversal, the development of the steroidogenic function of the gonads proceeds in the opposite direction to its natural development: in males, oocytes appear and steroid activity shifts from the stroma of the gonads into granulosa and theca; in females, on the contrary, secretory activity in the follicular membranes decreases and increases in the stroma of the gonads. Practical significance: the results of the analysis will give insight into the nature of sex steroid hormones, their dynamics in the blood, and their role in the implementation of various processes of gonadogenesis and gametogenesis before their practical use in fish farms.
