Authors: Likaj Ermal , Mehmeti Alessia , Dumani Selman , Mana Fjorba , Kuci Saimir , Bejko Ervin , Veseli Aferdita 
Published: January 2025

Introduction: This paper compares the David and Yacoub procedures for valve-sparing aortic root replacement, two leading techniques for treating aortic root aneurysms while preserving the native aortic valve. Both methods aim to avoid prosthetic valve replacement and the need for lifelong anticoagulation.
Material and Methods: We reviewed the technical nuances, clinical outcomes, and long-term durability of each technique, incorporating findings from recent and historical studies. Also, we'd like to present two case reports from our clinic showing the application of the David procedure.
Results: The David procedure involves complete excision of the aortic root and reimplantation of the native aortic valve within a Dacron graft. It offers superior long-term durability and lower reoperation rates, particularly in younger patients and those with connective tissue disorders. In contrast, the Yacoub procedure entails partial root resection and remodeling with preservation of the sinuses of Valsalva, making it a viable option for older patients or those with isolated root dilation.
Conclusions: Both the David and Yacoub procedures are advanced techniques for aortic root replacement, each with unique advantages and challenges. The David procedure, with its excellent durability, has consistently delivered successful outcomes. It is especially beneficial for younger patients and those with connective tissue disorders, supporting its role as a preferred approach for long-term outcomes in this population.

Published: January 2025

Introduction: The demand for reoperation on the aortic valve in Albania is rising, mirroring the increasing average age of the population and the subsequent rise in patients requiring aortic valve surgery. This trend underscores the need for this informative article, which aims to provide insights into the risks and outcomes of aortic valve reoperations, particularly in light of efforts by interventional cardiologists to expand the indications for TAVR to younger and lower-risk patients. Data from the Society of Thoracic Surgeons (STS) National Database reveal results that warrant attention, with concerns over reoperations after TAVR growing, mainly due to the uncertain feasibility of repeat TAVR.
This article presents a novel perspective on the risks associated with surgical aortic valve replacement (SAVR) after prior TAVR or SAVR. It underscores the urgent need to develop an optimal strategy for managing these patients and offers fresh insight.
Material and Methods: Our research, based on a comprehensive analysis of data from the Society of Thoracic Surgeons in the USA's 10-year database, included individuals who underwent bioprosthetic SAVR following prior TAVR and/or SAVR. Our analyses, which included total and isolated SAVR groups, focused on the primary outcome of operative mortality, ensuring the reliability and thoroughness of our study.
Results: The study included 31,106 patients who underwent SAVR. Among them, 1,126 had prior TAVR (TAVR-SAVR), 674 had undergone SAVR followed by TAVR and SAVR (SAVR-TAVR-SAVR), and 29,306 had undergone prior SAVR (SAVR-SAVR). Matched analysis for isolated SAVR cases showed a 1.74-fold higher operative mortality for TAVR-SAVR than SAVR-SAVR (P = 0.020). In our center, 5 cases have been performed in the last two years with excellent results, no losses, and operating times close to the first-time interventions.
Conclusions: This study's findings significantly contribute to the field. They could influence clinical practice, particularly for patients with longer life expectancies and anatomy unsuitable for TAVR. They suggest an initial SAVR approach may provide better results even in necessary surgical re-interventions on the aortic valve.

Authors: Grigoriev Sergey N. , Masterenko Dmitriy A. , Pimushkin Yaroslav I. , Stebulyanin Mikhail M. 
Published: January 2025

The article is devoted to increasing the volumetric accuracy of multi-axis machine tools. Based on the model of measurement and calculation of the volumetric geometric error of machine tools presented by the authors, a method has been developed which allows to signifi cantly improve the accuracy of the movement of the operating unit of a three-axis metal-cutting machine tool to a given point. The astatic law and the calculation of the coordinate correction according to the differential geometric model of the volumetric error are used to control the movement of the operating unit. The developed method is implemented programmatically and allows to perform the correction in the control program represented in G-code. As a result of experiments on software correction of volumetric errors according to the developed method, conducted at the State Engineering Centre of the Moscow State University of Technology “STANKIN” on a threeaxis CNC machine tool, a signifi cant reduction (up to 90 %) of geometric volumetric errors was shown. The developed method can be used to improve the accuracy of metal-cutting machine tools by creating postprocessors that calculate corrections to the coordinates set in the control system based on the results of interferometric measurements.Keywords: volumetric accuracy, interference measurements, three-axis machine tools, machine tool accuracy, geometric errors, astatic control law, mathematical modelling, differential geometry

A PARTICIPAÇÃO DA ELITE ALEMÃ NO HOLOCAUSTO
Authors: Veloso Rodrigo Felipe 
Published: January 2025

Esta resenha de O Engenheiro da Morte, de Marcio Pitliuk busca discutir sobre a escrita do romance histórico pautada por um crime horrendo e assustador que deixou marcas inigualáveis e transformou toda a sociedade mundial. O Holocausto trouxe consequências irreparáveis e dizimou milhões de judeus. Nesse sentido, em O Engenheiro da morte podemos ver não apenas o discurso histórico, num tempo específico, mas a realidade dos fatos que ocorreram e que requer transmissão para a sociedade contemporânea no intuito de ressignificação e alerta ao discurso antissemita e de ódio que assola o contexto social. No romance em apreço, a ambição e a corrupção no interior nazista revela as várias faces da identidade humana. As personagens Carl Farben e Martina Kaufmann sediam e organizam planos contrastivos no que tange ao extermínio de judeus e, o anseio de justiça por atos desumanos cometidos. Nessa ordem, o engenheiro Farben ambiciosa poder e desenvolve produto que pemitirá assassinar milhões de pessoas a baixo custo para o Reich. Por outro lado, Kaufmann, mulher judiã alemã que se mantém escondida durante o Holocausto e, posteriormente, anseia por justiça a quem cometeu tamanha atrocidade e extermínio. Portanto, trata-se de uma leitura que privilegia grandes doses de elementos históricos que servem como denúncia e que estão misturados ao ficcional nessa composição literária, bem como ainda registra os diálogos da ideologia nazista e a pugência de que as memórias da guerra devem sempre ser lembradas.

Vitamin D Supplements Overdose Toxicity: A Review Article
Authors: Abbas Zainab Abdul Kareem , Zahraa Ch. Hameed  , Sarah Alwan Malik Al-Yasiri  
Published: January 2025

Hypervitaminosis D, also known as vitamin D toxicity, is an uncommon but serious condition that occurs when the concentration of vitamin D is much higher than the body needs due to taking large doses of its supplements instead of the diet or even exposure to sunlight. The body regulates the amount of vitamin D entering it as a result of exposure to sunlight. one of serious consequences of vitamin D toxicity is accumulation of calcium in the body, which causes symptoms of nausea, vomiting, weakness, & frequent urination due to (hypercalciuria). These symptoms may develop to extend to bone pain & kidney problems such as calcium stones. This condition is treated by stopping taking the vitamin and reducing foods that contain a lot of calcium, as appropriate treatments are prescribed by the doctor and are given in the form of intravenous fluids & medications such as Corticosteroids or Bisphosphonates. When taking (60,000) IU of vitamin D daily for several months it is considered toxic because this level is much higher than the permissible and recommended limit by Recommended Dietary Allowance (RDA), which is 600 international units of vitamin D daily. In certain cases, higher doses than permitted are used to treating some medical conditions, such as severe vitamin D deficiency, but they must be taken under the supervision of a doctor and at a specific time, while monitoring calcium levels.

Published: January 2025

Briket adalah bahan bakar padat yang berbentuk gumpalan-gumpalan arang yang terbuat dari biomassa (bahan lunak). Namun, biomassa tersebut perlu diolah terlebih dahulu agar menjadi bahan bakar yang memiliki kadar panas lebih tinggi dari arang biasa. Selain itu, keunggulan briket adalah residu atau sisa hasil pembakaran yang lebih sedikit, asap yang dihasilkan lebih sedikit, ekonomis, dan tidak beracun. Dalam penelitian ini limbah dari ampas tahu dan sekam padi dimanfaatkan sebagai bahan bakar dengan cara mengubahnya menjadi briket. Penelitian ini bertujuan untuk mengetahui pengaruh perbandingan komposisi bahan baku dan persentase perekat tepung tapioka terhadap kualitas briket yang dihasilkan.

The present article aimed to study the secular changes in the mean adult human height of males and females across different regions of Russia. Here we present the results of the meta-analysis of a comprehensive data set on the mean heights of males from the 1900–1910s to the 1990–2000s birth cohorts among 63 regions of the Russian Federation (in over 470 groups), and mean heights of females from the 1940–1950s to the 1990–2000s birth cohorts among 54 regions of the Russian Federation (in over 340 groups). The regional secular trends of mean height were illustrated for the adult population in seven federal districts in Russia. We analyzed anthropological data using a combined approach, in which the temporal aspects of variation in body height were studied through retrospective analysis, and the spatial aspects (regional differences in adult height over a long period) were studied using cross-population analysis. The positive secular trend of the adult body height of men and women throughout the 20th century can be observed both at the national and subnational levels. During the last century, adult height of males increased by 9,35 cm (from 166,33 cm to 175,68 cm) at a rate of 0,84 cm/decade. From the 1940–1950s to the present, women’s adult height increased by 3,75 cm (from 160,06 cm to 163,81 cm) at a rate of 0,78 cm/decade. In our study, we found regional trends of secular dynamics and differences in mean height in different time slices. At the early 20th century, men of the Far Eastern Federal District exhibited the highest mean height, and at the end of the observation period this distinction was held by the men of Moscow and Krasnodar Krai. In the middle of the last century, the highest female height was documented in Pskov Oblast and Volgograd Oblast, and in the end of the century — in the Krasnodar Krai and Altai Krai. Regional differences in the spatiotemporal variation in adult human height may be explained by socio-economic differentiation between the subjects of the Russian Federation.
Transformation of Traditional Oriental Medicine in the Modern World
Authors: Kharitonova Valentina I. 
Published: January 2025

The article examines one of the most important modern issues concerning the development of traditional medicines: their transformation into TMS — traditional medical systems. It is known that in some Asian countries (China, India, Vietnam, etc.) such TMS legitimately exist since the middle or end of the XX century; they are institutionalized and structured similarly to the conventional/biomedical healthcare system. TMS operates there in parallel with and in close interaction with the main medical system, with biomedicine as the primary educational basis for specialist training. Healthcare in these countries includes in its unified system a parallel with a second ministry or department, a complex structure of university training of specialists, specialized hospitals and clinics of various kinds — either separate or organized on the basis of complementarity, different pharmaceutical bases. At the same time, TMS, primarily from India and China, have long since spread to many other countries of the world and, as complementary or alternative forms of medicine, strive to form global forms (for example, the concept of “global Ayurveda” is already being used).
The article first of all considers the specifics of the terminological apparatus associated with non-conventional medicine. Further the author analyzes the current situation of TM and TMS as it has developed to date in foreign countries, and compares it with what has been happening in the last three decades in the Russian Federation, primarily in the Republic of Buryatia and the Zabaykalsky Krai. Traditional medicine was initially introduced there with the practice of Buddhist lamas and with written sources from Tibet through Mongolia; later the Buryats on the basis of translated sources developed a relatively independent branch of Buryat-Tibetan medicine, which back in the XIX century spread first to St. Petersburg, and then to other cities and regions of the Russian Empire. Nowadays, in the main centers of traditional medicine in Buryatia and the Zabaykalsky Krai, the institutions of a medical system have been formed, making it possible to create a full-fledged TMS — a parallel, but closely intertwined with biomedicine branch of healthcare, which can easily become an alternative branch of healthcare in the Republic of Buryatia, where the traditional Buryat-Tibetan medicine has been institutionalized within the healthcare system since the 1980s. Currently, the Center for Oriental Medicine and its units are receiving a significant number of combatants for rehabilitation and are actively working in the field of restorative medicine.
