Relative contribution of the ocean-air heat exchange and advective heat transport to the increase of the Barents Sea water temperature in the early 21st century
Authors: Sumkina A. A. , Smirnov A. V. , Kivva K. K. , Ivanov V. V.
Published: September 2024

The annual water temperature in the major water masses of the Barents Sea (BS) has significantly increased since the early 2000s. Advective heat transport from the neighboring water areas and heat exchange through the sea surface are the major factors, which shape the hydrological conditions in the BS. The paper estimates the contributions of heat exchange at the sea-atmosphere boundary and advective heat transport to changes in the average water temperature of the BS for the entire sea area. The average annual heat balance of the BS is calculated using atmospheric and oceanic reanalysis data. The change in the average temperature of the BS water is estimated taking into account the heat consumption for ice melting. The average surface heat balance from 1993 to 2018 was negative throughout the entire sea area: –70…–100 W/m2 in the south and –10…–20 W/m2 in the north. The advective heat supply was calculated for 9 straits with neighboring water areas. The determining source of advective heat is the influx of Atlantic waters from the Norwegian Sea between Cape Nordkapp and Bear Island. An average of 40.8 TW of advective heat is supplied through this margin. The calculations showed the predominance of annual heat influx due to advection over heat loss from the sea surface. This excess heat influx resulted in an estimated increase in the water temperature of the BS from 1993 to 2018 at a rate of 0.28 °C per year (taking into account the heat consumption for ice melting). In conclusion, it can be argued that the analysis has validated the hypothesis proposed in the article about compensation of heat losses from the surface of the BS by advective heat flow. The hypothesis is quantitatively confirmed by calculations on a simple box model (with an accuracy of up to an order of magnitude) based on atmospheric and oceanic reanalysis data. The ERA5 and GLORYS12V1 reanalysis data reliably describe the basic patterns of observed variability of ocean, sea ice and atmospheric parameters in the Barents Sea.

Т. In recent decades, the distribution and activation of thermodenudation, which leads to the formation of specific landforms — thermocirques (also referred to as retrogressive thaw slumps, RTS), have been intensively studied. In different regions of the cryolithozone and at different time intervals, both activation and stabilization of thermocirques are observed. As a rule, studies focus on the climatic controls of the phenomena observed, the environmental controls are discussed less often. This study presents an analysis of the dynamics of thermocirques in relation to the relief features in a specific key area of Central Yamal. To achieve this aim, the spatial distribution of thermocirques at different geomorphological levels is considered based on multi-temporal remote sensing data. Satellite images obtained in 2009, 2018, and 2023, as well as a global digital elevation model (ArcticDEM), were used. We outlined five geomorphic levels and determined their parameters: area, altitude, steepness, and the aspect of the slopes. Thermocirques were identified in the images and their parameters were measured. The dynamics of the thermocirques were analyzed by their number, area, length, width, slope aspect and angle for the periods 2009–2018 and 2018–2023, and for 14 years in total, separately for each geomorphic level. It was found that thermocirques predominate on the slopes of the III alluvial-marine plain, 5–12° steep. In 14 years, the total area of thermocirques increased by 296 %, and their number — by 61 %. A larger increase in the total area and number of thermocirques occurred during the period 2009–2018 in response to climate extremes in 2012 and 2016. Thermocirques that face west cover a higher total area, partly due to the predominance of such slopes over the area of the key site. In all the years of observation, the average areas and lengths of thermocirques are maximum on south-facing slopes. Some of the results are close to those obtained in other regions of Russia and in North America. In many of the areas studied, the increase in the total area of thermocirques exceeded the increase in their number, which means that the expansion of the existing forms prevails over the inception of the new ones. The discrepancies observed in different studies in the results of assessing the effect of relief on thermocirques are due to both the regional features and differences in satellite imagery and methods of its processing.

The development of the Northern Sea Route and the beginning of year-round transit shipping require not only the production of new icebreakers and ice-class vessels, but also the development of a specialized hydrometeorological support system for ice shipping. For the analysis of satellite data and the development and validation of ice forecasts, actual field data on the ice cover is required. This data can only be obtained from shipboard observations; however, scientific expeditions are rarely organized during the winter. In order to obtain new data over the area of intensive shipping, two expeditions were organized on board of nuclear icebreakers in the southwestern Kara Sea (“LED-SMP” expeditions) in 2023 and 2024. Specialized hydrometeorological maintenance of ice shipping in the southwestern Kara Sea together with the research expeditions “LED-SMP” carried out in the same place and time on board the nuclear icebreakers revealed the influence of the technogenic factor on the sea ice structure and dynamics was revealed. In winter and spring, two main routes are used for navigation in the southwestern Kara Sea: through the Kara Gate Strait and north of Cape Zhelaniya. In April 2024, a unique situation occurred when, due to the difficult ice conditions east of the Kara Gate Strait, the entire ship traffic was directed north of Cape Zhelaniya. In preparing a long-term ice forecast, it was noted that after the redirection the natural development of ice processes changed. At the beginning of the winter period 2024,
Influence of quasi-biennial oscillations (QBO) on the stratospheric polar vortex in the Antarctic
Authors: Gabis I. P.
Published: September 2024

For many years, the dominant opinion in the literature has been that the stratospheric polar vortex is weaker in the easterly phase of the QBO than in the westerly phase, which is known as the Holton–Tan effect. While for the Northern Hemisphere vortex this is true during winter, for the Southern Hemisphere vortex the dependence on the QBO is observed only in spring. This feature is usually explained by the greater intensity of the Southern Hemisphere vortex compared to the Northern Hemisphere vortex, and the QBO can modulate its strength only during the vortex breaking season in October-November. Usually, the vortex response to the QBO is determined based on the equatorial wind direction at a certain vertical level, and the conclusions depend strongly on the level at which the QBO phase is determined. However, it has long been shown that using the equatorial wind sign at one or even a combination of several levels is not quite correct because it does not take into account the time of descent of the QBO wind relative to the seasons of the year, and it is not known at what altitudes the QBO wind has the strongest influence on the extratropical stratosphere. Due to the variable period of the QBO cycles, the phase relationship between the seasonal cycle and the QBO cycle is constantly changing, resulting in many variants of the vertical structure of the wind QBO during the Antarctic winter vortex and ozone hole. However, the seasonal regularities of QBO used in this work lead to a strictly limited number of possible variants of coincidence of the phases of the QBO cycles with the seasons of the year, which allows us to reveal typical features of interannual variations of the polar vortex and ozone hole in the Antarctic that are due to the QBO. The analysis of observational data indicates unexpected peculiarities of the QBO modulation of the stratospheric polar vortex in the Antarctic. The QBO effect in the vortex intensity is observed not only in spring during the weakening phase of the winter vortex, but also during the vortex maximum in June–August. At the same time, changes in the wind speed of the vortex during its maximum in winter are opposite to those in the spring during the ozone hole period. If the winter vortex is more intense (weak), then during the ozone hole period the vortex is weaker (more intense) than the average level.

Learning Arabic is a learning that most people consider difficult, because Arabic is inseparable from the science of nahwu. And the basis of nahwu knowledge that is commonly used by Islamic boarding schools is the book of Jurumiyah, because the book is considered the simplest and easiest to explain and usually the learning of the book of Jurumiyah is carried out in Islamic boarding schools but this is done in madrasas or formal institutions, and every learning must have advantages and disadvantages, one of which is in the study of the book of Jurumiyah. The formulation of this research problem is how the learning process of the book of jurumiyyah for grade 9 students at Mts Islamiyah Sukoharjo Plemahan Kediri, as well as the advantages and disadvantages of learning the book of Jurumiyah for grade 9 students at Mts Islamiyah Sukoharjo Plemahan Kediri. This study uses a qualitative research approach that is descriptive. Research Place at Madrasah Tsanawiyah, grade 9 students at Mts Islamiyah Sukoharjo Plemahan Kediri. The data sources came from the school principal, the teacher of the teacher, the Arabic teacher and the 9th grade students. The method of data collection uses observation, interviews and documentation. The results of the research on the study of the book of jurumiyah for grade 9 students at Mts Islamiyah Sukoharjo Plemahan Kediri have the goal of providing students with a basic understanding of the rules of nahwu used in Arabic, in the learning of the book of Jurumiyah the teacher uses the bandongan method. As for the reason for using this jurumiyah book because this book is the most famous book in all circles and the easiest for beginners or beginners, this jurumiyah learning is carried out 1 time for 1 week and has been included in the madrasah curriculum. Meanwhile, the advantages in the learning process of the book of Jurumiyah students are able to understand qowaid correctly. And the shortcomings in the learning process of the book of Jurumiyah are that the material taught focuses on qowaid so that students do not delve too deeply when learning Arabic.
Teenage language: use and abuse
Authors: Nicolosi Alessandra
Published: September 2024

The paper examines teenage language and how it expresses itself in unique ways to help define identities among peer groups. Teenagers challenge linguistic conventions to set themselves apart from adults by using a particular speech pattern that helps them identify and maintain their group identification. This study explores the psychological and social variables that influence the lexical features of teenage language among Turkish teenagers between the ages of fourteen and fifteen.
The study analyses the spoken language of three Turkish teens over the course of two weeks, focusing on their vocative use, word creation, and cursing. The results show that in order to express their uniqueness and challenge societal conventions, this group of Turkish youths deliberately violates linguistic standards. Their overuse of swearing and the creation of new vocabulary emphasize their drive to set themselves apart from adults and create a sense of collective identity.
The study also reveals how the English language and social media have influenced Turkish teenagers' language, as demonstrated by the use of Anglicisms and the creation of new terms related to sexuality and social media. According to the study, teenagers who group together are better able to communicate their uniqueness and use distinct languages.
Uygur Bozkır İmparatorluğunun Çöküşüne Manihaizm mi Neden Oldu?
Authors: Ozbay Betul
Published: September 2024

Mezopotamya’da doğan ve kısa süre sonra bu topraklardan sürgün edilen dini inanç Manihaizm’le Eski Uygurlar 8. yüzyıl ortalarında Bögü Kağan’ın hükmü sırasında tanışmışlardır. Kağan’ın Eski Türk âdetlerine oldukça yabancı olan bu yeni inanç sistemini neden kabul ettiği sorusu ise çeşitli teoriler ortaya atılsa da uzun süre yanıtsız kalmıştır. Hatta bu inancın ilkelerinin, Eski Türklerin beslenme ve yaşam düzenine aykırı olması Bögü Kağan’ın kararının nedenini anlaşılmaz kılmıştır. Diğer yandan, son yıllarda yapılan çeşitli çalışmalar bu kararın daha çok ekonomik gerekçelerle alındığına işaret etmektedir. 8-9. yüzyıllarda İç Moğolistan’da yaşanan kurak mevsimler, Uygurların güçlü müttefikler bulmasını mecbur kılmış görünmektedir. Manihaizm’de misyonerlik ve tüccarlık genellikle birbiriyle çok yakın ilişkili olduğundan bu dini, ticaretten tamamen ayırmak mümkün değildir. Manihaizm dini aracılığıyla Eski Uygurlar, Orta Asya’nın zengin tüccarları Soğdlarla doğrudan temas kurabilmişler, ekonomilerini ve ordularını güçlendirmişlerdir. Bununla birlikte, devlet içindeki yöneticilerin birbirleriyle yaşadıkları aralıksız çekişmeler ve büyük boyların isyanlarının Uygur Bozkır Kağanlığını çöküşe sürükleyen gerçek nedenler olarak öne çıktığı görülmektedir. Bu çalışmada, Manihaizm’in Orta Asya’daki durumu, din ve ticaret ilişkisi ile Eski Uygurların son yıllarında yaşanan çatışmalar ve şiddetli kuraklık üzerinde durularak tarihi çok katmanlı değerlendirmenin gerekliliği tartışılmıştır.
Gender Inequality and Collective Action in School Committees: Evidence from Tanzania
Authors: Manara Kenny
Published: September 2024

The making of education governance reforms has led to the transfer of school management powers to teachers’ and parents’ representatives through primary school management committees. However, the committees have been found to be inadequate in ensuring that collective action is taken by their male and female members in most low- and middle-income countries. In response, this paper examines the possibilities that collective action by school committees is related to gender inequality, controlling for demographic and socio-economic factors across the rural (Iringa District) and urban (Arusha City) contexts of Tanzania. The results of a simple linear regression analysis using Ordinary Least Square techniques show that gender inequality predicts the collective action in school committees in both Arusha City and Iringa District. However, the multiple linear regression model predicts gender inequality in Arusha, and not in Iringa, controlling for membership experience and occupational status for both the rural and urban samples. This paper has implications for both policy and practice. In particular, the next round of school autonomy reforms needs to consider the criteria for school committee membership to incorporate membership experience and occupational status into the qualifications of parents’ representatives. In practice, head teachers need to devise innovative, sustainable approaches using the readily available resources to provide planning, budgeting and monitoring skills-based training to newly elected parent representatives.

Published: September 2024

This comprehensive scoping review aimed to identify and synthesize the existing research on professional development (PD) for educators and educational leaders in the United Arab Emirates (UAE) between 2018 and 2023. Fourteen scholarly articles covering a wide range of topics related to education in the UAE were collected and analyzed. The review revealed that PD initiatives in the UAE often focus on enhancing teacher effectiveness and leadership skills, particularly in the context of educational reforms and inclusive education practices. However, significant challenges were identified, including implementation gaps, cultural barriers, and resistance to centrally imposed PD programs. The findings suggest that while PD programs positively impact teacher performance and educational quality, further efforts are needed to address the challenges within the UAE’s unique socio-cultural context.
Entangled in Regional Geopolitics - Tibetans in the Special Frontier Force of India
Authors: Datta Karubaki
Published: September 2024

The Special Frontier Force (S.F.F.) was raised by the Intelligence Bureau of India in the immediate aftermath of the Indo China war of 1962. Initially composed of Tibetan youths, it was known as the Establishment 22. Records indicate that it was raised by India in coordination with US intelligence Agency, the C.I.A. and with full endorsement of Washington. The force was trained by C.I.A., among other things to collect intelligence from across India’s China border with the help of electronic devices. The C.I.A. patronage was gradually withdrawn after 1964. In India, the force was commissioned to action in Chittagong Hill tracts in 1971, on the eve of Indo Pakistan War over Bangladesh issue. Later they took part in Operation Bluestar in Punjab and fought in the war of Kargil in 1999. Their activities and operations had so far been kept under total secret. Recently they were employed by the Government of India in the border faceoff with China in Ladakh in August 2020. The death of Nyima Tenzin of S.S.F. turned the spotlight on them and their sacrifice was highlighted. The importance of the S.F.F. in India’s security set up has to be understood in the context of the regional geopolitics and India’s Tibet policy. The force was raised in the era of Cold war when the C.I.A. was helping the Tibetan resistant warriors, the Chushi Gandruk, fighting from Mustang in Nepal. India, too was ready to help them even if covertly, to get back Tibet’s political status. Raising of the force gave not only a job opportunity to the Tibetan refugee youths but served their nationalist aspirations and suited India’s need of a trained mountain force post 1962 to combat China in the Himalayan region. But following the withdrawal of the C.I.A., Sino US rapprochement in the 1970s and the subsequent end of the Cold War, the priorities changed in the US and India’s policy towards China also went through several phases. The recent deterioration of relations with China has once again brought Tibetan issue to the limelight. India’s recognition of the S.F.F. actions in the war indicates how India, in order to put pressure on China is giving space to the Tibetan CTA (The Government in Exile, in India) and the Tibetans in S.F.F. The Tibetans have not been able to achieve independence but they are now being used in the political rivalry of the two regional powers.
The United States Role of the Occurrence of Violence in Cyprus
Authors: Aslim Ilksoy
Published: September 2024

Cyprus used to be under occupation of the foreign states for many centuries and sovereignty usually with few exceptions was not transferred peacefully. As it is well known, in the 19th century, use of force in international relations was seen as normal. In the 1878 however, transformation of sovereignty in Cyprus from the Ottoman Empire to the United Kingdom (UK) was by peaceful means. The UK ruled Cyprus mostly in peace until the uprising in 1931. The upheaval of the Greek Cypriots against the UK was to unite Cyprus with Greece (Enosis). The uprising was settled by violence and the constitutional rights suspended immediately. In 1955 when the riot of the Greek Cypriots occurred again this time the UK was successful to get support of Türkiye and the Turkish Cypriots and converted the anti-colonial struggle to the ethnic strife. Clearly, the occurrence of violence in Cyprus in 20th Century begun during the British period but it continued after the colonial period. Although the United States (US) refrained direct involvement to Cyprus problem it assisted to the formation of the Republic of Cyprus by 1960s. During the Cold War conditions, the US had to involve to the Cyprus problem because of two reasons: Firstly, in order to prevent a war between Türkiye and Greece, the two “motherlands” of the Turkish and Greek Cypriots; secondly to stop the violence between two local communities. In Washington DC the US leadership met with Greek and Turkish prime ministers in 1964 and they decided to solve the Cyprus problem forever. In Geneva the US representative had several meetings with the officials of Greece and Türkiye. There, the US former secretary of state offered his plan that included the use of violence for the dissolution of the Republic of Cyprus. The US plan could not be implemented at the time but after 10 years, its spirit became the source of the violence in Cyprus. In this study mainly the role of the US in occurrence of violence in the island will be studied.

Development of the theory and principles for planning multiproduct manufacturing activity of machining and assembly
Authors: Bochkarev Pyotr
Published: September 2024

Instructional guidelines for planning a multiproduct manufacturing activity (MA) for machining and assembly aimed at solving currently existing problems of machining industries process design, i.e. subjectivity of making design decisions, insufficient automation, and inability of the observing of current production situation are presented. The objective reasons for the need to improve approaches to the development of MA are the long cycle of the process design period, the low quality of the processes operation, and the impossibility to adjust MA at the implementation stage. The main structural elements of multiproduct manufacturing activity planning are described. Based on a systematic approach, all stages of work on technological support of production systems are combined, making possible to use the information arrays of data on the real state of the production system and operational information on production tasks in a short time frame. The results of theoretical work provide for the process of making MA as a system that combines the design and implementation of technology, taking into account the impact of changes in the production situation. In the process of approbation and use of the presented methodological approaches, significant areas of research were identified, smoothing away difficulties connected with the performance targets, enabling the development path of the system. Among them: the interaction with the design preparation of production; detailing data on the initial workpieces in connection with the choice of the MA structure and the appointment of a rational set of technological equipment; determining the requirements for technological equipment, focused on ensuring the flexibility of their use; determining the correlations between the multiple-path design of parts manufacturing process and the requirements for accuracy indicators in the assembly of products. The developed formalized models for the implementation of the stages of technological preparation of machining industries are a background for full automation of MA design and highly efficient functionality of machine-building complexes.
System-synergetic analysis and synthesis of a controlled cutting process
Authors: Zakovorotny Vilor , Gvindzhiliya Valeriya
Published: September 2024

Currently, good progress has been produced in the creation of machine tools with CNC computer systems. They are able to ensure the coincidence of program and the trajectories of the actuators with high accuracy. But when manufacturing parts with the same accuracy it becomes possible in rare circumstances. This is because of the necessity to take into account the entire controlled dynamic cutting system when manufacturing parts, while the quality of the part depends on various physical interactions under process work. In contrast to the well-known research and development, the paper focuses on the fact that the modeling level is based on a system-synergetic representation, which includes the procedure of expansion – compression of the state space. The system takes into account elastic deformations of its elements, evolutionary changes in their properties, uncontrollable disturbances, revealing physical interactions. This is a complex system, where its individual coordinates of the state depend on programmable trajectories first of all, secondly, they are characterized by internal connections and self-organization, and finally, they affect the output properties of cutting. The output properties include parts quality parameters and specified costs for parts manufacture. The article describes the main provisions of the synergetic system analysis and synthesis of a dynamic cutting system control, provides its mathematical modeling, views a simple procedure for analyzing and synthesizing a model. The example of practical application has been also observed.

Authors: Vasiliev Viktor , Alexandrova Svetlana
Published: September 2024

The article shows the importance of information (digital) technologies in a successful high-tech enterprise. The directions of development of quality management tools and methods for knowledge-based innovative processes and productions at various stages of the product life cycle are analyzed. The most important methods are the digitalization of the collection, storage and analysis of large amounts of data, the control of production and management processes, the construction of a product lifecycle management system based on modern information technologies. To implement new approaches to the manufacturing process management, digital transformation is used - the process of transformation of a company aimed at forming a unified information environment throughout the product lifecycle, combining various methods and tools for data management at the enterprise. An important step in the development of data processing technology is the use of artificial intelligence and neural networks. Alongside with the development of information technology, the possibilities of analytics from descriptive to prescriptive and cognitive are also growing. Based on the analysis of best practices in quality management, it can be concluded that it is possible and necessary to digitalize knowledge-based processes with a transition to more efficient methods of organizing production and quality management.
Production of composite materials in additive manufacturing
Authors: Grigoryants Aleksandr
Published: September 2024

The main possibilities of obtaining new composite materials are presented. Due to the high dynamics of thermal deformation processes in the molten bath of a thin layer of the grown part, we obtain a new material structure from immiscible components. Another direction of obtaining a new composite material in the growing process is the reinforcement of the matrix with high-strength elements, which can be present, including in the form of a solid phase under melting and crystallization of the material. This allows predicting in advance new qualitative properties of the grown part - increased strength, weight reduction, etc. Additive technology is being developed for growing parts and products made of tungsten, molybdenum, tantalum, niobium and other hard-melting metals that are poorly treated through mechanical methods. In this case, heating is used within growing process. The successful application of additive technologies is used in medicine in the manufacture of implants made of molybdenum, tantalum and their alloys, which have high biocompatibility and no toxic property. It becomes possible to manufacture an implant grown according to a specific model for a given individual. The main directions of the additive manufacturing development are the creation of more productive complexes and the expansion of construction materials powders range, used when forming new composite materials in the growing process.

Background: spinal cord injury leaves as a sequel in the acute and chronic period, deficiencies in the stability of joint functions and in the function of voluntary movement control. Those with good trunk control have a greater probability of carrying out activities of daily living by themselves; up to now, we do not have reliable tools in Argentina that evaluate trunk control in these subjects. 
Objectives: to cross-culturally adapt the trunk control test to Argentinean Spanish in subjects with sequelae of spinal cord injury and to establish interobserver and intraobserver reliability.
Methodology: the subjects were admitted using a non-probabilistic convenience sampling. Subjects who were between 15 and 75 years old and had a diagnosis of spinal cord injury were included. Subjects who had: another neurological diagnosis, alteration in sensory organs, conditions that prevent the performance of the test, and psychiatric illness were excluded.
Results: 30 subjects were included for cross-cultural adaptation and 55 for reliability. Semantic modifications were made to all items and response options. The intraobserver and interobserver reliability of the scale or subdomains did not achieve a sufficient score.
Conclusion: the trunk control test was adapted cross-culturally to Argentine Spanish and interobserver and intraobserver reliability was established. The adaptation was achieved through semantic changes and the reliability was not sufficient. In the future, studies should be carried out to improve the reliability and study the validity of the tool.

Tracheostomy (TQT) has emerged as a valuable alternative for patients with orotracheal intubation, especially those under prolonged mechanical ventilation (VMP), as in the case of chronic obstructive pulmonary disease (COPD). This population presents additional challenges, and the available information regarding their progression in specialized centers is limited in Argentina.A descriptive, retrospective, and cross-sectional study was conducted at Santa Catalina Neurorehabilitation Clinic between August 2015 and December 2018. Patients with COPD referred to the Intensive Care Unit (ICU), tracheostomized, and subsequently referred to the Center for Ventilation Disconnection and Rehabilitation (CDVMR) were included. Cases with missing data or derived from other CDVMRs were excluded. Clinical records and interviews were employed to collect demographic and progression data.Out of the 27 COPD patients included (4.9% of 555), the majority were males (63%) with an average age of 68.1 years. Most were admitted with AVMi, and 11 (45.8%) were successfully disconnected, while 11 (40.7%) were decannulated. Survival and home discharge were more frequent in decannulated patients (81.8% were discharged) compared to non-decannulated ones (50% deceased, and none were discharged).COPD patients undergoing TQT and VMP, who succeed in being decannulated, seem to have better prospects for survival and home discharge compared to those who do not have the cannula removed. There is a suggestion for the need for additional analytical studies to confirm these findings and improve the understanding of this specific population.

Introduction: The importance of knowing the impact of work on people's health has increased after the COVID-19 pandemic. Burn Out (BO) syndrome arises from the tension emerging from the conflictive interaction between the worker and his or her employment. The objective was to describe the prevalence and frequency of diagnosis of BO in the health human resources of critical services of the Bahía Blanca Municipal Hospital in the context of the COVID-19 pandemic.Methods: Descriptive, cross-sectional study. The study population was the medical and nursing staff of the Intensive Care (IT), Emergency Medicine (SMU) and Clinic services who worked with COVID-19 during 2021. The Maslach Burnout Inventory (MBI) questionnaire was used and complementary closed questions to identify, among these cases, those that were diagnosed and treated by the institution.Results: Of the 219 workers, 55.3% (121/219) were nurses. In the SMU, 25% (24/96) of respondents had BO, followed by 20.4% (11/54) in Clinic and 8.7% (6/69) in IT (p value=0.004). Only 5.5% (12/219) of the total were diagnosed with BO by the institution and of this group, two people (0.9%) had previously consulted for characteristic symptoms.Discussion: A high prevalence of BO and a marked underdiagnosis were evident at the institutional level during the pandemic. Although the IT Service had the highest demand for attention, it was the one that presented the lowest BO values in relation to other services.
Cardiomiopatía cirrótica – ¿Realidad clínica o simple curiosidad académica? Revisión.

Hepatic transplantation (HT) is the standard of care of end-stage liver disease with Cirrhotic Cardiomyopathy (CCM), but medical treatment with combination of diuretics and non-selective beta blockers are important before and after that. Owing to its particular pathophysiology unlike another etiologies of heart failure, in CCM angiotensin-converting enzyme inhibitors (ACEI), angiotensin II type I receptor blockers (ARB), and angiotensin receptor neprilysin inhibitor (ARNI) are not recommended. Transjugular intrahepatic porto-systemic shunt (TIPS) has indications in CMM but its potential benefits and risks must be considered and more researh is necessary. HT is a demanding therapy but the most effective one, and showed improvement in QTc, diastolic and systolic dysfunction; in recent decades, in spite of more severe ill patients (more severe MELD score), survival has improved significantly due to better surgical techniques, intensive care, immunosupresive drugs, and images.

Published: September 2024

Background: Hernia through Winslow's hiatus, known as Blandin’s hernia, a rare but potentially life-threatening condition, represents a diagnostic and therapeutic challenge. This case report describes a successful laparoscopic approach to a cecum hernia through the foramen of Winslow in a 63-year-old female.Case Presentation: The patient presented with 24 hours of abdominal pain and nausea. Abdominal CT scan revealed a herniated cecum and terminal ileum compressing the gastric chamber and portal vein, leading to periportal edema. Laparoscopic right colectomy was performed after successful colon content evacuation via the greater gastric curvature to facilitate reduction. This was done to aid in reduction, as there were indications of non-viability in the right colon. The procedure unfolded without complications.The patient developed postoperative abdominal collections requiring percutaneous drainage but recovered well and was discharged within two weeks.Conclusion: This case highlights the value of laparoscopy in managing foramen of Winslow hernias, offering minimally invasive benefits. Early diagnosis through imaging tools like CT is crucial for prompt surgical intervention and preventing complications like intestinal ischemia or perforation.

Published: September 2024

The study addresses the translation, cross-cultural adaptation and initial validation of the Oldenburg Burnout Inventory (OLBI) questionnaire into Spanish, particularly for the context of health personnel. The OLBI, based on the Job Demands - Resources Model, evaluates burnout and job disengagement. After a rigorous methodological process, two versions of the questionnaire were carried out, followed by a pilot test and cognitive interviews. Comprehension problems were identified in a question related to work disconnection. Adjustments were made to the final version, which was validated with a multiprofessional pediatric palliative care group. The results showed adequate reliability for the Exhaustion scale and acceptable for the Disconnection scale. The importance of considering the particularities of the work context in adapting the instrument was highlighted. Although limitations, such as sample size, are acknowledged, it is suggested that the OLBI – UY version is promising and can be used in future studies for a more comprehensive psychometric analysis. This study represents an original contribution by addressing the adaptation of a relevant instrument for measuring burnout in Spanish-speaking health personnel in the Río de la Plata.

Background: Surgical complications are preventable in up to 50% of cases, actually are various tools to avoid them, one of these are morbidity and mortality conferences. However, there are no guides that define their structure for them to be effective. Objective; Analyze the impact of a new modality of surgical conferences in a sector of benign biliary pathology, called quality evaluation conferences. Methodology: Descriptive observational study where the overall improvement of the sector, the decrease in complications and the quality of patient care are compared. For 6 months, a weekly quality evaluation conference was carried out. It had 5 stages; 1. Analysis of all discharged patients. 2. Review of adverse events. 3. Review of the list and order of patients in the surgical plan. 4. Reproduction of recorded surgeries and review of scientific articles. 5. Review of own scientific works in development. Results: after implementing the conferences, there was a decrease in the number and severity of complications, as well as an improvement in the correct and timely surgical indication. Conclusion; Quality evaluation workshops as an evolution of morbidity and mortality workshops are a novel tool that, when well implemented, can help improve quality standards and in turn be used as a learning option in training centers.
