Strike-slip kinematics from crustal to outcrop-scale: the impact of the material properties on the analogue modelling
Authors: Massaro Luigi , Adam Jürgen , Jonade Elham , Negrão Silvia , Yamada Yasuhiro
Published: October 2024

Abstract. Strike-slip fault zones commonly display complex kinematics and 3D geometries, with high structural variability along strike and with depth. In this regard, analogue modelling techniques represent a powerful tool for investigating the structural, kinematic and mechanical deformation processes at various scales. In detail, dynamically scaled experiments allow the direct comparison between model and natural systems. The geometric scaling factor defines the model resolution, in terms of model/prototype length equivalence, and depends on the mechanical and physical properties of the prototype and analogue materials. In this paper, systematic strike-slip experiments were performed by applying four different model materials to investigate the deformation dynamics at various scales and to highlight the impact of the physical and mechanical properties of the model material on the experiments. The applied model materials showed a non-linear strain-dependent deformation behaviour while providing different dynamically scaled geometric scaling factors. Digital Image Correlation (DIC) analyses of the experiments allowed a quantitative comparison of the displacement and strain fields at different stages of the dextral displacement above a single planar basement fault. The analysis of the localisation and development of the fractures in the strike-slip shear zones enabled the comparison of the different structural styles and dynamics observable at various levels of resolution. Therefore, the application of such a multi-scale approach in dynamically scaled experiments can provide new insights into the investigation of complex deformation processes with analogue modelling techniques.

Authors: Schaffer Laura , Boesch Andreas , Baehr Johanna , Kruschke Tim
Published: October 2024

Abstract. Storm surges pose significant threats to coastal regions, including the German Bight, where strong winds from north-westerly directions drive extreme water levels. In this study, we present a simple, effective storm surge model for the German Bight, utilizing a multiple linear regression approach based solely on 10 m effective wind as the predictor variable. We train and evaluate the model using historical skew surge data from 1959 to 2022, incorporating regularization techniques to improve prediction accuracy while maintaining simplicity. The model consists of only five terms, namely the effective wind at various locations with different time lags within the North Sea region, and an intercept. It demonstrates high predictive skill, achieving a correlation of 0.882. This indicates that, despite its extreme simplicity, the model performs just as well as more complex models. The storm surge model provides robust predictions for both moderate and extreme storm surge events. Moreover, due to its simplicity, the model can be effectively used in climate simulations in future studies, making it a valuable tool for assessing future storm surge risks under changing climate conditions, independent of the ongoing and continuous sea level rise.

Published: October 2024

Abstract. Water is an essential nutrient for living beings and is fundamental to metabolic processes. Under free-living conditions, primate individuals can use different strategies, skills, and resources to access water. Here, we report on observations of water consumption in Ateles chamek and Sapajus apella; describe the environmental conditions in which such events were observed, as well as the behavior of the individuals; and compare these observations with similar records in neotropical primates. Water consumption was observed during primate surveys in a forest fragment of approximately 52 ha bordered by the Jaru River, located southwest of the Brazilian Amazon, Vale do Paraíso municipality, state of Rondônia, Brazil. To access water, individuals of A. chamek used their tails, whereas S. apella used a leaf as a tool. Our observations suggest that tree holes may be important water sources for primates in forest fragments and that individuals of different species use different strategies to collect water from tree holes. Access and consumption strategies are directly associated with different cognitive skills and behaviors, which may include using tools, as in the case of capuchins. As water consumption records are limited, these findings highlight the need for continuous reporting to better understand water acquisition. Such reports are especially needed in the context of fragmented and degraded habitats, where water availability is affected by edge effects and the reduction in both fleshy fruits and moisture, which are important for primate species.

Authors: Qadir Muhammad Favad , Muhammad Mahmood Ali
Published: October 2024

The subwavelength grating microring resonator based filter shows great promise in optical sensing and communication. However, it spectrum nature makes it unsuitable for tracking or extracting a single wavelength from a broadband light source. In this paper, we used side-mode suppression, based on an angular grating- subwavelength microring resonator which offer high flexibility in wavelength design within the silicon-on-insulator (SOI) waveguide. By periodically arranging silicon waveguide pieces in three different widths, we can set the effective index along the inner sidewall of subwavelength microring resonator. thereby can achieve the  precise wavelength selection. We examine the effects of various key parameters on the center wavelength, side-mode suppressed ratio, and quality factor of this filter.The proposed structure's isalso analysed for coupling strength between the bus and subwavelength grating ring resonator. The wavelength selection, compact size, compatibility with other similar nature waveguide-based devices and design flexibility highlight its significant potential in compact optical sensing and optical communication

Social Media is a very powerful tool for establishing communication between the population and the government, as well as improving the efficiency of Public Administration. The use of social media in public administration is a new phenomena with numerous advantages and disadvantages. Despite the fact that it became widely used in Kazakhstan in recent years, there has been little research on the subject. Therefore, this research work aimed at identifying the extent to which state bodies exploit the potential of social media to generate two-way communication in addition to delivering information, and to find out about citizen engagement with the government. The study employed two quantitative research approaches. The social media pages of regional governments (akimat of Turkestan region, akimat of West Kazakhstan region) on Instagram and Facebook were analyzed, and as the second method, a survey was conducted among users of social media in Kazakh and Russian (105 people participated). According to the study's findings, the government mostly uses the potential of social media to distribute information, rather than as a means of two-way communication. On the social media pages that were the object of the study, engagement of the population is very low, with only 3-4 comments written in each publication on average. Although these institutions create content on a regular basis, research has revealed that the great majority of content does not pique the public's attention or spark debate. Keywords: information, communication technologies, social media, social network, digital development, public administration, "hearing" state, content analysis.

The article considers topical issues of regional development in the Republic of Kazakhstan in the context of income inequality and economic growth. Regional inequality in Kazakhstan is a topical issue that affects various aspects of the population's life and the country's development. The purpose of this article is to analyze the uniformity of the distribution of economic indicators by regions of the Republic of Kazakhstan. For this purpose, the Lorenz curve and the Gini coefficient were used, which made it possible to analyze the uniformity of the distribution of two important economic indicators by regions: gross regional product (GRP) and regional budget revenues. The results of the analysis showed the uneven distribution of GRP depending on the population of the region. As a result of the analysis, the authors determined that the distribution of income between regional budgets is more uniform than the distribution of GRP. Thus, the formation of the size of regional budgets per capita has almost absolute equality. Keywords: regional budget, gross regional product (GRP), inequality, Lorenz curve, Gini coefficient.

When studying tile revetments of monuments in Iran from the late twelfth to the mid-fourteenth century and in the fifteenth-century Ottoman Empire, one is faced with two very different narratives as to how the design and production of these revetments came about. The luster tiles installed in Iran and beyond were produced in one city, Kashan, by well-documented families of tile-makers who left a wide range of signed tiles and vessels. Tiles produced in the Ottoman Empire between the 1410s and the 1470s are attributed to the “Masters of Tabriz,” an elusive group construed to be a multi-generational, itinerant workshop based on a single signature on the mihrab of the mosque-zāviye of the Ottoman sultan Mehmed I (r. 1413–21) in Bursa (1419–21). In a comparative study of these two contexts, this article offers insights into ways of producing and logistics of transporting and installing large-scale tile revetments, and argues that in the Ottoman case, too, production may have taken place at a single site.

Несмотря на значительные успехи в хранении водорода с использованием наноматериалов на основе углерода, таких как углеродные нанотрубки (УНТ), попытки значительно увеличить емкость хранения водорода все еще не приносят желаемых результатов. В этом исследовании рассматривается влияние эндоэдральных атомов никеля на удержание атомов водорода в одностенных углеродных нанотрубках (ОУНТ) при различных температурах с использованием моделирования реактивной молекулярной динамики (МД). Результаты показывают, что эндоэдральные атомы никеля усиливают хемосорбцию водорода на поверхности ОУНТ при температурах выше комнатной. В частности, увеличение объемной доли атомов никеля в ОУНТ приводит к увеличению порядка связи до 2.69%, росту среднего парциального заряда до 17.24% и увеличению гравиметрической плотности до 3.08%. Полученные результаты дают представление о механизмах, с помощью которых эндоэдральные атомы металлов могут улучшить емкость хранения водорода в УНТ, что способствует разработке более эффективных и практичных технологий хранения водорода.
Mechanisms for forming methylglyoxal complexes with benzene and ethanol molecules. Nonempirical calculations
Authors: Norkulov A.
Published: October 2024

The formation mechanism of methylglyoxal monomers, dimers, trimers, methylglyoxal+benzene, and methylglyoxal+ethanol complexes was investigated using the density functional theory (DFT) approach and the B3LYP/6-311++G(d, p) functional set. Methylglyoxal has two C=O stretching vibrations, and in solvents, the intensity of the first C=O vibration band increased sharply, and the intensity of the second C=O vibration band decreased. This is due to the C=O···H hydrogen bond formed between methylglyoxal+benzene/ethanol solvents. Also, the calculations showed that among the molecules of methyglyoxal+benzene/ethanol mainly weak interactions, i.e. Van der Waals interactions, play a dominant role. Calculations are shown the complex formation energy increases as the number of molecules increases, but the average hydrogen bond energy corresponding to each bond remains unchanged. Also, the DFT method was used to study molecular structure, quantum chemical parameters such as Mulliken atomic charge distribution, atoms in molecules (AIM), reduced density gradient (RDG) and noncovalent interaction (NCI), electron localization functions (ELF), and localized orbital locator (LOL).
MEASURING GLOBALIZATION: ANALYZING INTERNATIONALIZATION OF HIGHER EDUCATION (IOHE) THROUGH STEM EDUCATION IN PAKISTAN
Authors: Fatima Tuz Zahra  , Urooj Aijaz  , Dr Talat Sharafat Rehmani
Published: October 2024

The concepts of 'internationalization' and 'globalization' are closely intertwined, impacting both tangible and intangible aspects of higher education. Internationalization refers to the internal transformations that occur within an educational setting as a result of frequent cross-border interactions within a local governmental system. Currently, developing countries like Pakistan are adapting and shaping their higher education systems in response to the global knowledge economy but neglecting the introduction of STEM education in the areas of social sciences like mathematics, statistics, entrepreneurship, IT, and other courses that are considered the need of time may leads to lack social scientist’s ability to estimate & forecasting and critically evaluate the situations as these deficiencies lead to reduce the cognitive skill of the workforce. This qualitative study employed Wallenstein’s World System analysis framework to examine student mobility and educational policy aspects in Pakistan critically. The findings suggest that the internationalization of higher education may lead to unequal exchange of educational services between core and peripheral countries in the global system.
LEADERSHIP CRISES AND FAILURE OF POLITICAL PARTIES A HISTORICAL PERSPECTIVE OF ISOLATION OF EAST AND WEST PAKISTAN
Authors: Dr. Nasir Abbas  , Kashif Imtiaz Khan  , Muhammad Ramzan Rimzi
Published: October 2024

the inception of Pakistan on the map of the world as a result of the partition of all India, the dominancy of the Western part of Pakistan was very clear but un-understandable. The political parties and leaders from the West Pakistan always thought themselves superior to that of East Pakistan. This behaviour of the political parties and the leadership from the West Wing gave birth to hatred among the subjects belonging to the East Pakistan. The political Parties and the leadership never tried to take such steps which could create harmony among the masses of the both sides. As the time passed, hatred increased. The reflection of these hatred emerged in the general elections, held on 1970.Awami League led by Sheikh Muji-Ur-Rehman secured 160 seats out of 162 seats allocated for the East Pakistan but unfortunately, it failed to win even in a single constituency of the West Pakistan. On the other hand, PPP led by Zulfiqar Ali Bhutto, secured a marginalised victory of 81 seats out of total 138seats allocated for the West Pakistan but it did not participate in East Pakistan. These unexpected results further divided the parties and leadership because the West Pakistan was not ready to give its dominance in the hands of the East Pakistan while there was an absolute majority of the East Pakistan and constitutionaally, the rule was to be given to Awami League. Whereas, the leadership of that time is concerned, they were not ready to solve the rift politically. The problems increased; Pakistan had to go into war with India in 1971.As a result of this political chaos and anarchy Pakistan had to face humiliation in the war. The East Pakistan separated from the West Pakistan and emerged as an independent country on international sphere, known as "The Republic of Bangladesh". This study also unwraps some shroudedl things such as, West Pakistan's genocism act against the East Pakistanis and the Indian roll of taking part into the matter of Pakistan, which became an immediate factor for physical separation of Pakistan. The study uncovers how Indian intervention into the burning matter, reinforced the already existing variables, paved a way for the creation of Bangladesh. Para oxically, foreign agents such as the USA,USSR and China had a very bounded and limited impact on the sources and upsurge of the East-West isolation.

Published: October 2024

Apart from YouTube and Instagram, new e-commerce live streaming platforms have emerged (TikTok Shopping, Amazon Live), which opens new opportunities for engaging with the audience and driving sales. Women, looking for an emotional and interactive experience, tend to make impulse purchases during live broadcasts. That is why it is necessary to investigate this topic. The purpose of this study was to examine the psychological factors that influence women’s impulse purchases while watching live broadcasts and to determine the psychological characteristics of women who make impulse purchases during live broadcasts. The study included questionnaires and interviews with women living in the Philippines, East Timor, Thailand, Singapore, Myanmar, Malaysia, and Laos. The key findings are that the study revealed the psychological factors of influence and psychological characteristics of women as they make purchases during e-commerce live streams. Psychological characteristics include emotionality while watching (68.3% of respondents), fear of missing out on a good deal (58.3% of respondents) and being influenced by other viewers and streamers (74.2% trust recommendations). Psychological factors include a set of technological and social components. Technological factors include interactivity and real-time communication (56.7% consider it significant); visual appeal and product display (71.7% consider it significant); and the convenience of shopping while browsing. Social factors include parasocial interaction with the streamer, a sense of community with other viewers (63.3%). The study also identified the role of hosts, which plays a significant role in building trust in the product and online platform: building trust in the product and brand (74.2% trust recommendations); influence through charisma, expertise, and attractiveness (62.5% consider them attractive, 58.3% – competent). Live broadcasts effectively stimulate impulse purchases among women. Emotions, trust, and social influence play a key role in this process. The practical significance of this study lies in the possibility of helping women to better understand the factors that influence impulse purchases, to avoid the influence of emotional stimuli and social pressure. The findings of this study can be used to develop recommendations on how people can effectively shop online

Over the past decades, intensive work has been carried out to expand the possibilities of aesthetic dentistry; the range of demands from patients has also increased. One of the main conditions for the long service life of filling material is careful oral care using the full arsenal of available hygiene products. We analyzed the effect of mouth rinses with various active ingredients (fluorine, chlorhexidine digluconate, medicinal plant extracts) on the level of oral hygiene, as well as on the quality of the filling, in particular on the color of the aesthetic restoration after their use. At the end of the study, all subjects experienced a significant improvement in oral hygiene (decrease in API scores). However, a negative effect of a liquid product containing chlorhexidine digluconate (Waterdent “Chlorhexidine mouthwash with mint flavor”) on the quality of composite restorations has been established. The use of additional oral hygiene products can reduce the risk of caries, but their selection must be personalized so as not to have a negative impact on the aesthetics of composite restorations.

The purpose of the experiment. Experimental modeling of craniofacial injuries, analysis of oculomotor function and regeneration in the post-traumatic period. Materials and methods. In the experiment, 48 sexually mature males of the Wistar breed were hit with a blunt hammer on a pre-determined area on the muzzle. According to the MS CT data, the nature of the displacement of bone fragments and the presence of muscle interposition were visualized. In the post-traumatic period, behavioral activity in the Actimeter device was analyzed. Results and discussion. Taking into account the thickness of the bone, the localization of the buttress at the place of applied force in the rodent, the hypothesis of energy absorption with its propagation through the bone structures of the orbits, and their subsequent displacement, was confirmed. Conclusions. In 38% of animals (groups 2 and 4), after impact to the postero lateral segment of the lower wall of the orbit, type 2 fracture of the cheekbone-orbital complex was recorded. In the posttraumatic period, a violation of behavioral activity was registered, which required prompt correction of displaced fragments. Upon impact to the central segment, in 50% of cases, 1 type of fracture was formed, without deviations in behavioral activity and without the need for surgical treatment.

Published: October 2024

Orthodontic treatment with aligner systems is a relatively new treatment option for patients with distal occlusion. The small number of publications on the issue of improving and improving this type of treatment, as well as the lack of information about the possible amounts of movement and rotation of teeth during treatment with aligners, became the motivation for this study. A retrospective study was conducted based on the treatment protocols of 193 patients. Descriptive statistics methods were used for the selected group of patients. The real movements/rotations of the crowns and roots of teeth were assessed immediately after successful treatment by patients. The improvement and advancement of orthodontic treatment with the aligner system is that it is now possible to compare the treatment plan for that particular patient with the statistical distribution presented in this paper for exceeding the limit (third quartile) of translation or rotation. Exceeding the limit (third quartile) will signal to the attending orthodontist that the doctor should pay attention to this extreme movement/rotation and, if possible, adjust the treatment plan.

Abdominal compartment syndrome is a severe pathology requiring special preventive and treatment measures. The development of methods for the prevention of abdominal compartment syndrome is important in patients with W3 ventral hernias and loss of the domain. The study analyzed the results of treatment of 71 patients with W3 hernias of the anterior abdominal wall. Before surgery, all patients were calculated the size of the hernia implant necessary for the prevention of compartment syndrome. To calculate the size of the required hernia implant, radiography, ultrasonography and anthropometric data of the patient were used. The patients underwent hernioplasty with sublay, inlay and, developed by the authors, in a combined method. In the groups with inlay and combined method hernioplasty, the development of compartment syndrome was not observed. The combination of the developed methods of preoperative calculation of the hernia implant and the combined method of hernioplasty showed a low number of early and late postoperative complications, the same as in other study groups. The results obtained indicate the effectiveness of the developed methods for the prevention of abdominal compartment syndrome.
The Use of Robot-Assisted Trepan Biopsies of Retroperitoneal Tumors under the Control of Multispiral Computed Tomography
Authors:   Belgorod Regional Clinical Hospital of St. Joasaph, Pustovgar Andrey A.
Published: October 2024

Various types of tumors, both benign and malignant, can be localized in the retroperitoneal space, which can develop not only in retroperitoneal organs, but also originate from nerves, connective or lymphatic tissue. Their pathomorphological diagnosis is relevant for the appointment of adequate treatment. There is a technique of percutaneous core-biopsy of such formations under the control of multispiral computed tomography, most often carried out by the "free hand" method. However, high radiation exposure not only to the patient, but also to the interventionist doctor are its negative sides. The author has developed a robotic device that automatically inserts a biopsy needle into the "place of interest". It was used for diagnostic punctures in the retroperitoneal space in 24 patients. In the control retrospective group, punctures were performed using the "free hand" method in 20 patients. The authors reveal an enhancement of the accuracy of puncture in the main group, a reduction in the amount of complications and of the duration of manipulation. The latter, along with the exclusion of radiation exposure to medical personnel, made it possible to reduce it on the subject.

The purpose of the work. To study the change in acid-base balance in the oral cavity in various variants of the course of acute pancreatitis. Materials and methods. On the basis of GUZ "City Clinical Hospital No. 1" and GUZ "Regional Clinical Hospital" Chita for the period 2021-2023, a single-stage study was performed, which included 95 patients (n=95) suffering from acute pancreatitis of varying severity aged 15 to 80 years. At admission, the pH of saliva was measured using litmus strips from EKROSCHEM LLC, St. Petersburg. Statistical processing of the obtained results was carried out using the SPSS Statistics 11.0 program in compliance with the principles of statistical analysis adopted for research in biology and medicine. In order to assess the correlation and determine the closeness and direction of the correlation between the two features, Spearman's criterion was used. When comparing the study groups and the clinical comparison group, the Student's criterion with the Bonferroni correction was used. Results. As a result of the study, it was found that in patients with acute pancreatitis, the pH of saliva is shifted to the acidic side of 4.2-6.2 with an average value of 5.4 ±0.4. At the same time, in patients with acute pancreatitis, a shift in the acid-base balance of saliva towards its acidification was revealed as inflammatory and destructive changes in the pancreatic parenchyma increase. This established fact is of particular interest for the timely diagnosis of the severity of acute pancreatitis.

Intra-abdominal bleeding is a leading cause of adverse outcomes in liver trauma, underscoring the critical importance of timely surgical intervention and optimal hemostasis strategies. This study investigates the impact of liver model segmentation on the distribution of mechanical stresses during impact simulation using the finite element method. By discretizing a computer-aided design (CAD) model into finite elements of two types – 4-node linear isoparametric elements for the parenchyma and 3-node Kirchhoff plate elements for intersegmental partitions – we developed a computational liver model adequately captures the organ's anatomy. Our results show that incorporating segmentation significantly affects the simulation outcomes, enabling a more realistic assessment of tissue damage patterns upon impact. This approach facilitates the simulation of a wide range of real-world traumatic effects, allowing for arbitrary specification of impact direction, speed, and affected area. By accounting for liver segmentation, our study provides a more accurate and comprehensive understanding of traumatic liver injuries, ultimately informing clinical decision-making and improving patient outcomes.

Целью исследования является изучение показателей живой массы у бычков голштинской породы в оптимальный срок, принадлежащих к разным генотипам. Объектом исследования является бычки помесы первого поколение (Ғ1), полученные в результате промышленного скрещивания. В результате кормления бычков полноценными питательными веществами бычки помесы II группы (½ абердин-ангусской х ½ голштинской) Ғ1 имеют среднюю живую массу 514,1 кг, а их аналоги по сравнению с I группой (чистопородная голштинская порода), III группой (½ лимузина х ½ голштина) и IV группами (½ шаролезской х ½ голштинской) были выше на 51,7 кг (11,2%, Р<0,001), 9,8 кг (1,9%, Р<0,05) и 18,3 кг (3,7%, Р<0,01), соответственно. Среднесуточный прирост бычков II группы от рождения до 16-месячного периода роста составил 1009,4 г, что дало их сверстникам преимущество в 111,7 г, или 12,4% (Р<0,001), 33,6 г, или 3,4% (Р<0,01) и 57,1 г, или 6,0% (Р<0,01).<0,001), соответственно, по сравнению с бычками I, III и IV групп.

В статье представлены результаты определения влияния породной принадлежности телок и сезона года на морфологические показатели крови. Установлено, что в летний сезон года по сравнению с зимним периодом у телок всех пород отмечалось повышение концентрации гемоглобина и количества эритроцитов в крови и снижение числа лейкоцитов. При этом телки казахской белоголовой породы превосходили сверстниц красной степной и симментальской пород по количеству эритроцитов в крови в зимний сезон года соответственно на 8,26 % и 3,12 %, в летний период – на 10,00 и 3,75 %. Вследствие этого телки красной степной и симментальской пород уступали молодняку казахской белоголовой породы по концентрации в крови гемоглобина зимой на 10,07 % и 5,98 %, летом – на 12,72 % и 6,56 %. По количеству лейкоцитов в крови, содержанию минеральных веществ и витамина А в сыворотке крови существенных межгрупповых различий не установлено.

В статье приводятся результаты исследования развития волосяного покрова коров-первотелок. Объектом исследования являлись коров-первотелок: I – черно-пёстрая (чистопородные); II – голштины немецкой селекции (чистопородные); III – голштины голландской селекции (чистопородные); IV – ½ голштин немецкой селекции × ½ черно-пёстрая; V – ½ голштин голландской селекции × ½ черно-пестрая. Волосяной покров у животных разных пород имеет характерные особенности и изменяется под воздействием внешних факторов. Основной функцией волосяного покрова является тепло защитная. Характерно, что минимальными показателями волосяного покрова, как в зимний период, так и в летний сезон года отличались коровы-первотелки зарубежной селекции II и III групп, что вполне объяснимо. Голштинские помеси IV и V групп по развитию волосяного покрова, уступая коровам-первотелкам черно-пестрой породы I группы, превосходили чистопородных голштинских животных II и III групп. Это обусловлено проявлением эффекта скрещивания по величине анализируемых показателей.

Published: October 2024

The microbiota is a major topic of study nowadays. It has numerous roles in regulating host immunity, and its alteration, called dysbiosis, can cause numerous diseases. There are several therapeutic strategies to modulate the microbiota, from the use of pre- and pro-biotics to antibiotics. Dietary habits also seem to have a significant impact on modulating the gut microbiota. In this narrative review, we aim to investigate how diet influences the gut microbiome from early life through school age. We performed a search of available articles in the literature, published between January 2000 and January 2023, using the PubMed/Medline database, including children aged 0-5 years, using keywords relevant to the topic. The aim was to clarify how different types of diet that characterize the early years of life contribute to the formation of the individual’s gut microbiota.

Adolescence is an extraordinary, but also complex and disorienting time of life, for those who experience and for those who deal with it as adult caregivers, whether parent or health professional, as in our case. It represents a critical developmental stage of existence in which various lifestylerelated habits, positive or negative (eating habits, physical activity, smoking habits etc.), may become established and persist throughout adulthood [1]. Healthy nutrition is one of the basic pillars of primary prevention, plays an essential role in adolescent’s quality of life, and will help determine the state of good health in adulthood as well. This article describes the nutritional needs of adolescents and analyzes the difficulties encountered by medical professionals in communicating, motivating, and supporting them over time.
Le vaccinazioni nei bambini e adolescenti sottoposti a TCSE o TOS

In recent years in the Vaccination Centers there has been an increase in requests for vaccination in children and adolescents undergoing solid organ transplantation (HRT) or hematopoietic stem cell transplantation (HSCT), the latter performed to treat hematologic and metabolic diseases, but sometimes also used in some solid tumors. Vaccination-preventable diseases (such as influenza and pneumococcal disease) still cause significant morbidity and mortality in patients undergoing HRT and in those who have received HSCT [1,2]. An epidemiological study found that the incidence of invasive pneumococcal disease was 590/100,000 and 199/100,000 in allogeneic or autologous transplant recipients, respectively, compared with 11.5 cases/100,000 in an age-matched control population [3,4]. It is important to define the vaccination schedule based on immunosuppression and immunoreconstitution status. Subjects undergoing HRT require lifelong immunosuppressive therapy, but they have not undergone a conditioning regimen, as is the case in HSCT, which leads to the cancellation of the immunologic memory of previous vaccinationsvac [5]. Whatever the case, it is always important to immunize, in accordance with current guidelines, although the levels of protection

The Morbillo & Rubella News bulletin n. 74, July 2024, highlighted that the sudden increase in measles cases reported in the last four months of 2023 (33 cases), was accentuated in 2024: 717 cases in the period January-June, of which 605/676 unvaccinated, with 55 cases among Healthcare Workers, of which 41 unvaccinated. SIMEUP, the Italian Society of Pediatric Emergency and Urgency, believes it is essential that those responsible for safety in our Hospitals, from Directors to Competent Doctors, take action as soon as possible to prevent other HCW from being affected by vaccine-preventable infections, such as measles. The adoption of a vaccination protocol in compliance with existing laws and the clear indications of the Constitutional Court can encourage healthcare workers to adhere to immune prophylaxis, reducing the percentage of susceptible people and making hospital departments safer.
