Additive Construction Production: Past, Present, Future

An overview of the development of additive construction production from the beginning of the formation of prerequisites to the present moment and future prospects for the development of 3D construction printing in the world is given.The publications of international citation databases, including the results of research in the field of additive construction production for the period from 1972 to 2024, are considered as the basis of the study.The study is divided into several stages, the first of which is devoted to the analysis of search queries and the definition of relevant keywords.It was revealed that the most popular phrases describing the use of additive technologies in construction are “Concrete Printing” and “3D Concrete Printing”, therefore, as part of the subsequent stage of work, abstract samples were formed on their basis to analyze and summarize the results of relevant scientific research. The final stage of the study included a more detailed study of the main results of scientific works characteristic of three time intervals describing past, present and future trends in scientific activity in the subject area under consideration. The results of the study show a significant increase in interest in the technology of construction 3D printing with concrete due to the realization of the potential to increase labor productivity in construction and reduce the negative impact on the environment in comparison with traditional construction production technologies, which can become a driver of sustainable development of the construction industry.The conducted research makes it possible to conclude that there are still unresolved problems on the way of active implementation of the technology, which are constraining factors for the widespread introduction of additive construction production, in particular the issues of printing horizontal structures of floors and coatings of buildings, reinforcement of load-bearing structures printed with a 3D printer. According to the authors, the solution of these problems should be given priority in future research, along with the development of new formulations for 3D printing with concrete.

Spatially Resolved Analysis of Stellar Populations in NGC 2992: Impact of Active Galactic Nucleus Feedback

In NGC 2992, a galaxy-scale ionized gas outflow driven by active galactic nuclei (AGNs) has long been recognized, yet its impact on the host galaxy has remained elusive. In this paper, we utilize data from the archival Very Large Telescope/MUSE to present a spatially resolved analysis of stellar populations in this galaxy. Two different stellar population templates are employed to fit the stellar continuum, allowing us to determine the light-weighted stellar age, metallicity, the fraction of the young stellar population (age <100 Myr, P Y), and the average age and metallicity of P Y. Our results reveal the presence of a very young stellar population (≤40 Myr) within the dust lane and nearly along the galaxy’s major axis. The light-weighted stellar age and the fraction of P Y show negative trends along the major and minor axes. The average age and metallicity of P Y present positive trends with increasing distance, except along the northern direction of the major axis. Within the circumnuclear region (<1 kpc), the distribution of the young stellar population is spatially anticorrelated with the AGN outflow cone. The highest fraction of P Y is observed at the outskirts of the nuclear radio bubble in the northern region near the nucleus. Considering the coupling efficiency and timescales, we propose that the AGN outflow in this galaxy may exert both negative and positive feedback on its host. Additionally, the star formation and the AGN activities could be attributed to the interaction between NGC 2992 and NGC 2993.

Lung Cancer Screening-Trends and Current Studies.

Lung cancer is the leading cause of death among all the oncological diseases worldwide. This applies to both women and men; however, the incidence and mortality among women is on the rise. In 2020, lung cancer was responsible for 1.8 million deaths (18%). More than 90% of lung cancer cases and 77.1% of lung cancer deaths occur in countries with high and very high HDI (human development index) values. The aim of our study is to the present trends and most recent studies aimed at lung cancer screening. In the face of the persistently high mortality rate, conducting research aimed at extending already-implemented diagnostic algorithms and behavioural interventions focused on smoking cessation is recommended.

Extreme Seasonal Droughts and Floods in the Madeira River Basin, Brazil: Diagnosis, Causes, and Trends

The Madeira River, a major tributary of the Amazon River, often undergoes severe flood and drought conditions. This study seeks to investigate the climate processes associated with the opposing extreme precipitation events in the Madeira River basin and to relate them to river discharge variability based on a flood awareness dataset. Despite the uncertainty in the observational datasets, the annual precipitation cycle exhibits a rainy season from November to March. A significant result is the high correlation between the rainy season variability in the Madeira River basin and the sea surface temperature (SST) anomalies in the tropical North Atlantic Ocean and the southwestern South Atlantic Ocean. This result indicates that improving the Atlantic SST representation in climate modeling allows for capturing extreme precipitation events in the region. In addition to this impact, certain Madeira River tributaries present significant climate trends. The river discharge variability reveals an increase in hydrological extremes in recent years in the upper sector, but more significantly, in the lower basin, where it has reduced by more than 400 m3/s per decade. These findings highlight the need to improve in situ data and climate and hydrological modeling, with a focus on describing the intense climate variability and trends in river discharges.

The finding of the study reveals that climate change is affecting the Yartsaguubu abundance and livelihood of Yartsagunbu collectors.

Emerging Applications of Picture Archiving and Communication Systems and Their Impact on Research and Education: A Literature Review.

In recent times, technological advancements have remarkably improved picture archiving and communication system(PACS) capabilities beyond their conventional use in radiology departments. Researchers and instructors have started employing PACS functionalities to improve medical research processes, promote interdisciplinary collaborations, and facilitate learning. To illustrate this point further, the PACS enables researchers to handle and analyze huge amounts of imaging data with superior precision and speed, supporting innovative studies in areas like disease progression, treatment outcomes, and imaging modalities. Moreover, a PACSintegrated with artificial intelligence (AI) algorithms leads to significant improvements in image processing, diagnostic accuracy, and personalized treatment, thus marking a new approach to medical imaging. The PACSsupported by AI is mostly transformative since they allow for improved early disease detection capabilities as well as automated image processing and decision assistance, which increase diagnostic accuracy and clinical outcomes. Such systems can rapidly process large quantities of visual data with an accuracy rate surpassing earlier endeavors. In medical research, however, combining PACSwith AI allows challenging imaging datasets to be examined, thereby making findings that were not previously possible. The capacity to combine imaging outcomes with clinical information is valuable for medical students and professionals in the field of education. They can access extensive medical image collections and case studies using PACS. This link is critical for teaching and learning as it allows students to interact with concrete events and improve their diagnostic accuracy in a controlled environment. This review discusses how the PACS affects educational courses and clinical outcomes based on the available literature. Our aim was not only to outline recent research or developments but also to present a comprehensive overview regarding the growing role played by PACS in the modern healthcare system and academics. Similarly, we look at the challenges and opportunities associated with the wide adoption of PACS, highlighting possible future areas of study or teaching methodologies. Issues such as data security, interoperability, and the need for defined protocols are included to give an exhaustive understanding of what PACS can and cannot do. Through this study, we stress PACS's revolutionary potential in advancing research methodology and educational practices, eventually contributing to enhanced patient care and knowledge dissemination in healthcare areas. The continual growth of PACS technology and its applications is expected to reshape the landscape of medical research and education, making it a vital component in the quest for medical excellence. By knowing the present trends and future potential, stakeholders in healthcare and education may better employ PACS to reach their objectives and boost overall results.

Scenario Analysis of Socio-Economic and Climate Related Changes in Nutrient Load and Retention for the Pregolya River Catchment (South-Eastern Baltic): The View at the Beginning of 21&lt;sup&gt;st&lt;/sup&gt; Century

The study analysed the transboundary Pregolya River Catchment, covering both the Polish and Russian parts, using the HYPE hydrological module and FyrisNP emission-retention model. The results revealed significant spatial variations in nutrient retention. The data assessment indicates that, at the start of the 21st century, the nutrient load from the Polish part of the catchment is significantly greater than that from the Russian part. Model simulations based on climatic projections for the years 2041–2060, but with current nutrient loads, showed a significant level of uncertainty in the changes of nutrient export to the Baltic Sea. The range for total nitrogen was –10 % to +27 %, and for total phosphorus it was –29 % to –10 %. Model simulations based on different socio-economic scenarios, but current climate conditions, showed that if present 5-year trends are maintained, nutrient export will only increase slightly (3 % for total nitrogen and total phosphorus). If the plans for socio-economic growth of Polish and Russian local governments are implemented, including the expansion of agriculture in Kaliningrad Oblast, there will be a significant increase in nutrient export (78 % for total nitrogen and 55 % for total phosphorus).

Lamotrigine Emerging as a Driver of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: An 8-Year Retrospective Study

BackgroundStevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) represent severe manifestations of a potentially life-threatening spectrum defined by a desquamating rash of the skin and mucous membranes. This study was prompted by the observed increase in the off-label use of lamotrigine as a causal agent in SJS/TEN in our regional burn center. MethodsA retrospective cohort of 48 patients presenting to the Connecticut Burn Center from 2015–2022 with suspicion for SJS/TEN were reviewed for age, sex, causative drug, presenting symptoms, hospital course, biopsy confirmation, length of stay, comorbidities, and 30-day mortality. Descriptive statistical analysis was conducted to identify trends in causative agent, clinical presentation, and mortality. ResultsThirty patients in our cohort received a final diagnosis of SJS/TEN. While antibiotics remain the most frequent cause of SJS/TEN across the study period (33.3 %, n = 10), the incidence of cases attributable to lamotrigine increased from 1 case between 2015 and 2018 (6.7 %) to 6 cases between 2019 and 2022 (40 %). In 2020 alone, 50 % of all cases were attributable to lamotrigine (n = 4). Of the patients where lamotrigine was implicated, 71.4 % (n = 5) were prescribed lamotrigine for off-label use in the treatment of non-bipolar mood disorders. The average lamotrigine-associated SJS/TEN patient was younger (p < 0.001), had fewer comorbidities, and was more likely to be female than the general SJS/TEN population. ConclusionOff-label use of lamotrigine is emerging as a major driver of SJS/TEN with notable changes in patient demographics. Further research is necessary to understand how changing trends in the patient population will impact clinical course and optimal management.

Computer Vision Model Compression Techniques for Embedded Systems:A Survey

Deep neural networks have consistently represented the state of the art in most computer vision problems. In these scenarios, larger and more complex models have demonstrated superior performance to smaller architectures, especially when trained with plenty of representative data. With the recent adoption of Vision Transformer (ViT) based architectures and advanced Convolutional Neural Networks (CNNs), the total number of parameters of leading backbone architectures increased from 62M parameters in 2012 with AlexNet to 7B parameters in 2024 with AIM-7B. Consequently, deploying such deep architectures faces challenges in environments with processing and runtime constraints, particularly in embedded systems. This paper covers the main model compression techniques applied for computer vision tasks, enabling modern models to be used in embedded systems. We present the characteristics of compression subareas, compare different approaches, and discuss how to choose the best technique and expected variations when analyzing it on various embedded devices. We also share codes to assist researchers and new practitioners in overcoming initial implementation challenges for each subarea and present trends for Model Compression.

Women speaker representation at SAGES annual meetings: a cross-sectional analysis

BackgroundGender representation trends at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Annual Meetings and the effect of the 2018 ‘We R SAGES’ initiatives are unknown. We assessed gender trends in oral presentations at the SAGES Annual Meeting between 2012 and 2022 with a focus on assessing the impact of the 2018 initiatives.Methodss selected for oral presentations from 2012 to 2022 were reviewed for presenter and first, second, and senior author gender. Gender was categorized as woman, man, or unknown using public professional profiles. Subsequent publications were identified using search engines. The primary outcome was the temporal trend of proportion of women in each role using interrupted time series analysis. Secondary outcomes included publication rates based on first and senior author genders in 2012–2018 versus 2019–2022.Results1605 abstracts were reviewed. The proportion of women increased linearly in all categories: presenter (2.4%/year, R2 = 0.91), first author (2.4%/year, R2 = 0.90), senior author (2%/year, R2 = 0.65), and overall (2.2%, R2 = 0.91), (p < 0.01 for all). Prior to 2018, the proportion of women increased annually for presenters (coefficient: 0.026, 95% CI [0.016, 0.037], p = 0.002) and first authors (coefficient: 0.026, 95% CI [0.016, 0.037], p = 0.002), but there was no significant increase after 2018 (p > 0.05). Female second author proportion increased annually prior to 2018 (coefficient: 0.012, 95% CI [0.003, 0.021], p = 0.042) and increased by 0.139 (95% CI [0.070, 0.208], p = 0.006) in 2018. Annual female senior author proportion did not significantly change after 2018 (p > 0.05). 1198 (75.2%) abstracts led to publications. Women were as likely as men to be first (79% vs 77%, p = 0.284) or senior author (79% vs 77%, p = 0.702) in abstracts culminating in publications. There was no difference in woman first author publication rate before and after 2018 (80% vs 79%, p = 1.000), but woman senior author publication rate increased after 2018 (71% vs 83%, p = 0.032).ConclusionThere was an upward trend in women surgeons’ presentations and associated publications in the SAGES Annual Meetings over the last decade.

Evolving Trends in the Diagnosis and Management of Keratoconus Over 3 Decades.

To report the trends in the clinical presentation, diagnosis, and management of keratoconus (KC) in patients presenting to a multitier hospital network over 33 years. This retrospective study included patients with KC presenting from 1987 to 2020. Patients with KC in at least 1 eye were included. The data of 20,576 patients included in this study were retrieved from the electronic medical record database. Data on patient demographics, ocular diagnosis, contact lens usage, and surgical history were collected and exported for analysis. Descriptive statistics and chi square test were used for statistical analysis. A total of 20,576 KC cases were seen from 1987 to 2020. Mean age at diagnosis reduced from 29.3 years (1987-1991) to 22.2 years (2016-2020). Adults (76.64%) were commonly affected with a majority being male (61.25%). Use of contact lenses increased from 4.34% (2002-2006) to 11.23% (2016-2020). Of the total number of surgical interventions, collagen crosslinking (CXL) constituted more than 1/5th (22.28%) between 2007 and 2011, which increased to more than half between 2012 and 2016 (53.61%) and almost 3/4th (72.53%) between 2017 and 2020. Advances in lamellar surgery have led to more patients undergoing deep anterior lamellar keratoplasty (DALK) as compared with penetrating keratoplasty. In the last 8 years, 17.2% patients underwent surgery and the most common was CXL (14.77%) followed by DALK (1.72%) and penetrating keratoplasty (1.04%). We report the trends in the clinical presentation and management of KC over 3 decades. In the last 33 years, advances in diagnostics have helped diagnose KC earlier. Contact lenses and advances in CXL have reduced the number of keratoplasties in KC, DALK being more common.

Atrial fibrillation fact sheet in Korea 2024 (part 1): epidemiology of atrial fibrillation in Korea

Background and objectivesThis study aimed to analyze and present updated trends in atrial fibrillation (AF) epidemiology within the Korean population, providing a foundation for planning and implementing appropriate management and treatment strategies for patients with AF.Patients and methodsWe used the Korean National Health Insurance Service database to evaluate the prevalence, incidence, comorbidities, and clinical adverse outcomes of patients with AF in Korea between 2013 and 2022.ResultsAF prevalence in Korean adults aged ≥ 20 years doubled (1.1 to 2.2%) between 2013 and 2022, with significant increases observed across various sex and age groups. Similarly, the number of newly diagnosed patients with AF per year increased steadily, with the incidence rising from 184 to 275 per 100,000 person-years, particularly among older populations. Over this period, the mean age of patients with AF increased from 67.7 to 70.3 years, and comorbidities prevalence and CHA2DS2-VASc score rose significantly, indicating a higher stroke risk. Compared with patients without AF, AF was associated with an increased risk of mortality (hazard ratio [HR]: 1.78), ischemic stroke (HR: 2.39), major bleeding (HR: 2.10), myocardial infarction (HR: 1.44), and heart failure admission (HR: 2.42).ConclusionAF prevalence and incidence have steadily increased between 2013 and 2022, with a more pronounced increase in older patients. Patients with AF are increasingly becoming a high-risk population and are at increased risk of clinical adverse outcomes compared to non-AF patients. Therefore, a sustained national effort to improve AF awareness and comprehensive care quality for patients with AF is required.

1080 Evaluating the Impact of Bariatric Surgery Tourism on an Emergency Upper GI Service: A Case Series

Abstract Aim The number of individuals seeking weight loss surgery has been increasing globally. It is not uncommon for patients to travel abroad for these procedures due to various reasons, such as cost savings or availability. This audit identifies patients who underwent bariatric surgery abroad and subsequently presented to our hospital, observes trends in presentation, types and frequencies of complications, and management strategies employed. Method A retrospective case study of medical records of patients who presented acutely following gastric bypass, sleeve, or gastric band operations abroad between January 2018 to July 2023 was performed. Results A total of 21 patients were identified. 17 (81%) were female, with mean age 42.2 years. 15 (71.4%) patients presented between 2022-2023, and 5 (33.3%) of these were diagnosed with leak. 11 (52.4%) had undergone sleeve gastrectomy, 6 (28.5%) Roux-en-Y gastric bypass and 4 (19%) gastric band. Operations were performed in 11 different countries, with 10 (47.6%) performed in Turkey. The commonest presenting complaint was abdominal pain (71%). Average Length of stay was 9.1 days (range 1-45). 9 patients (42.9%) had multiple attendances (range 2-6). 7 (33.3%) underwent surgery; 3 laparoscopic removal of gastric band, and 4 emergency procedures for leak, involving either laparotomy and/or endoscopic therapy. Conclusions The number of patients presenting with complications of bariatric surgery tourism has increased year-on-year. This is leading to a growing burden on NHS resources. Healthcare professionals, policymakers, and patients themselves must be aware about the importance of follow-up when deciding to undergo weight loss surgery abroad. A national audit is also warranted.

Trends in Presentation and Management of Endogenous Hyperinsulinaemic Hypoglycaemia Over the Last Three Decades at a Tertiary Care Centre (1992-2022).

Endogenous hyperinsulinaemic hypoglycaemia (EHH) is characterized by inappropriate insulin secretion from pancreatic beta cells despite low blood glucose concentrations. We aimed to evaluate the secular changes in presentation and management of EHH due to insulinoma/non-insulinoma pancreatogenous hypoglycaemia syndrome (NIPHS) at our centre. This was a single-centre ambispective study (2014-2022). The clinical, biochemical, hormonal and radiological parameters (n = 63) collected as part of this study were compared with our earlier studies (1992-2005, n = 31; and 2006-2013, n = 35) and with other centres across the world. A total of 63 patients (39 males) with a preoperative diagnosis of EHH (insulinoma, n = 58; and NIPHS, n = 5) and a mean age of 40.7 years were studied. The mean lag time from the onset of symptoms to diagnosis decreased from 4.6 years during the first study period to 1.9 years during this study period. However, the majority presented with fasting hypoglycaemia of 98.4%, and both fasting and postprandial hypoglycaemia of 32%. Exclusive postprandial hypoglycaemia was present in 1.7% of insulinoma. A histopathological diagnosis of insulinoma was made in 52 patients and nesidioblastosis in two patients. Intraoperative ultrasonography (IOUS) and intraoperative palpation (IOP) yielded 100% sensitivity, while endoscopic ultrasonography (EUS) and 68Ga-DOTA-Exendin-4 positron emission tomography/computed tomography (PET/CT) yielded sensitivity of 86% and 85%, respectively, for localizing insulinoma. Resolution of hypoglycaemia was noted in 53 of 57 (93%) patients who underwent surgery with a preoperative diagnosis of insulinoma. We observed a trend towards earlier diagnosis of EHH, increased patient numbers and availability of nuclear imaging techniques for preoperative localization in the last decade compared to earlier.

EVOLUTION OF BELTS FROM BRONZE AGE TO MODERN FASHION STATEMENTS

Across history, belts have evolved from their practical beginnings to become potent emblems of prestige, style, and cultural expression. Belts have come a long way from their utilitarian origins as instruments for carrying weapons in the Stone Age to their current position as opulent fashion accessories. The historical development of belts is examined in this essay, along with their functions in prehistoric times, the Middle Ages, the Renaissance, and the Modern Era. It explores the social significance of belts, how their form and function have evolved, and how they have continued to impact fashion trends. The study also addresses future directions and present trends in belt design, including technical advancements, cultural influences, and sustainability initiatives. By use of a historical context and current development analysis, this paper delves into the history of belts and its future trends and advancements.

Modifiable factors to prevent severe hypoglycaemic and diabetic ketoacidosis presentations in people with type 1 diabetes.

In tackling rising diabetes-related emergencies, the need to understand and address emergency service usage by people with type 1 diabetes is vital. This review aimed to quantify current trends in presentations for type 1 diabetes-related emergencies and identify public health strategies that reduce the frequency of diabetes-related emergencies and improve glycaemic management. Medline (OVID), Cochrane and CINAHL were searched for studies published between 2000 and 2023, focusing on people with type 1 diabetes, severe hypoglycaemia and/or diabetic ketoacidosis, and ambulance and/or emergency department usage. There were 1313 papers identified, with 37 publications meeting review criteria. The incidence of type 1 diabetes-related emergencies varied from 2.4 to 14.6% over one year for hypoglycaemic episodes, and between 0.07 and 11.8 events per 100 person-years for hyperglycaemic episodes. Notably, our findings revealed that ongoing diabetes education and the integration of diabetes technology, such as continuous glucose monitoring and insulin pump therapy, significantly reduced the incidence of these emergencies. However, socio-economic disparities posed barriers to accessing these technologies, subsequently shifting the cost to emergency healthcare and highlighting the need for governments to considersubsidising these technologiesas part of preventative measures. Improving access to continuous glucose monitoring and insulin pump therapy, in combination with ongoing diabetes education focusing on symptom recognition and early management, will reduce the incidence of diabetes-related emergencies. Concurrent research assessing emergency healthcare usage patterns during the implementation of such measures is essential to ensure these are cost-effective.
