Knowledge Mapping of Macrophages in Osteoporosis: A Bibliometric Analysis (1999-2023).

Osteoporosis is a common metabolic disorder that significantly impacts quality of life in the elderly population. Macrophages play a crucial role in the development of osteoporosis by regulating bone metabolism through cytokine secretion. However, there is a lack of scholarly literature in the field of bibliometrics on this topic. This study provides a detailed analysis of the research focus and knowledge structure of macrophage studies in osteoporosis using bibliometrics. The scientific literature on macrophage research in the context of osteoporosis, retrieved from the Web of Science Core Collection (WoSCC) database spanning from January 1999 to December 2023, has been incorporated for bibliometric examination. The data is methodically analyzed and visually represented using analytical and visualization tools including VOSviewer, CiteSpace, Scimago Graphica, the Bibliometrix R package, and Pajek. In the last quarter-century, there has been a consistent rise in the quantity of scholarly publications focusing on the relationship between macrophages and osteoporosis, resulting in a total of 1499 research documents. These studies have originated from 45 different countries, with China, South Korea, and the United States being the most prominent contributors, and the United States having the highest frequency of citations. Noteworthy research institutions involved in this field include Shanghai Jiao Tong University, Wonkwang University, Huazhong University of Science and Technology, and Seoul National University. The Journal of Bone and Mineral Research is widely regarded as the premier and most frequently referenced publication in the field. These publications involve the collaboration of 8744 authors, with Lee Myeung Su contributing the most articles, and Takayanagi being the most co-cited author. Key emerging research focal points are encapsulated in keywords such as "mTOR," "BMSCs," "bone regeneration," and "exosome." The relationships between exosome from macrophage sources and those from BMSCs, along with the regulatory role of the mTOR signaling pathway on macrophages, represent crucial directions for future development in this field. This study represents the inaugural comprehensive bibliometric analysis detailing trends and advancements in macrophage research within the osteoporosis domain. It delineates recent frontiers and hotspots, providing valuable insights for researchers in this particular area of study.

Vitamin D Status and Cardiovascular Disease in College Athletes After SARS-CoV-2 Infection.

To evaluate the association between vitamin D status and CV disease after COVID-19 in college athletes. Retrospective cohort study. National College Athletic Association Division-I college athletes from a single academic institution. A total of 157 athletes (60 female; median age: 20 years) from 9 sports with a positive SARS-CoV-2 test, cardiac magnetic resonance imaging (CMR), and vitamin D level. Serum 25-hydroxyvitamin D level (primary); age, sex (regression models). Differences in age, sex, race, ethnicity, myocarditis, pericarditis, and CMR metrics by vitamin D status were analyzed. Regression models were used to assess the relationship between vitamin D status and CMR metrics accounting for age and sex. Low vitamin D (LVD) was found in 33 (21.0%) of athletes, particularly Black males (P < 0.001). Athletes with LVD had higher biventricular and lower mid-ventricular extracellular volumes, but these differences were not significant when corrected for age and sex. Athletes with LVD had higher left ventricle (LV) mass (P < 0.001) and LV mass index (P = 0.001) independent of age and sex. Differences in global circumferential strain were noted but are likely clinically insignificant. Vitamin D status did not associate with myocarditis and pericarditis (P = 0.544). LVD is common in athletes, particularly in Black males. Although athletes with LVD had higher LV mass, cardiac function and tissue characterization did not differ by vitamin D status. Future studies are needed to determine if the differences in LV mass and LV mass index by vitamin D status are clinically significant. This study suggests that vitamin D status does not impact the development of myocarditis or pericarditis after COVID-19 infection.

Clinicomicrobiological risk factors for infective endocarditis in viridans group streptococci bacteraemia.

When to perform echocardiography to rule out infective endocarditis (IE) in patients with viridans group streptococci (VGS) bloodstream infections (BSIs) is unclear. We aimed to identify independent risk factors for IE in patients with VGS BSI. This retrospective study conducted at Seoul National University Hospital from January 2013 to December 2022 involved patients with VGS and nutritionally variant streptococcal BSI, excluding single positive blood cultures and polymicrobial BSI cases. Independent risk factors were identified by multivariate logistic regression and sensitivity analyses according to echocardiography results, VGS species or the inclusion of possible IE cases. Of 845 VGS BSI cases, 349 were analysed and 86 IE cases were identified (24.6%). In the multivariate analysis, heart valve disease [adjusted odds ratio (aOR), 14.14, 95% CI, 6.14-32.58; P < 0.001], persistent bacteraemia (aOR, 5.12, 95% CI, 2.03-12.94; P = 0.001), age (per year, aOR, 0.98; 95% CI, 0.96-1.00; P = 0.015), solid cancer (aOR, 0.26; 95% CI, 0.13-0.53; P < 0.001) and haematologic malignancy (aOR, 0.04; 95% CI, 0.01-0.41; P = 0.006) were independently associated with IE. Sensitivity analyses yielded consistent results; also, infection by a member of the mitis group was independent risk factor for IE (aOR, 6.50; 95% CI, 2.87-14.68; P < 0.001). Younger age, heart valve disease, persistent bacteraemia, absence of underlying malignancy and BSI by a member of the mitis group were independent risk factors for IE in patients with VGS BSI. Echocardiographic evaluation could be prudently considered based on these clinicomicrobiological risk factors.

An Experimental Investigation of Low-Frequency Active Excitation in Scramjet Combustor Using a Micro-Pulse Detonation Engine

A micro-pulse detonation engine (μPDE) was designed and installed to a direct-connect scramjet combustor of Pusan National University (PNU-DCSC). The active excitation on the scramjet combustor was experimentally studied using the μPDE operating at frequencies of 10–20 Hz. A vitiation air heater (VAH) was used to supply high-enthalpy vitiated air to the isolator and the scramjet combustor at a Mach number of 2.0, with a total temperature of 1600 K and a total pressure of 1.68 MPa. The exit of μPDE was located at the center of the cavity of the scramjet combustor. Active excitation was performed at equivalence ratios of 0.111 and 0.163, and characteristics were analyzed through Schlieren recording and bottom wall pressure measurement. As a result, when the detonation emitted from the μPDE entered the scramjet combustor, it instantly formed a shock train and moved forward within the scramjet combustor. The flame instantaneously changed from the cavity shear layer flame to the cavity flame. Through bottom wall pressure measurement, it was also observed that active excitation resulted in a significant pressure increase near the cavity compared to when active excitation was not performed. This revealed combustion characteristics, indicating improved combustion efficiency from the pressure increase in the scramjet combustor.

Assessing dynamic co-movement of news based uncertainty indices and distance-to -default of global FinTech firms

Contemporary literature does not offer evidence on the causal relationship of default risk and investor sentiments for FinTech sector. We bridge this gap by assessing the dynamic co-movement between Distance-to-Default of leading global FinTech firms and three uncertainty indices namely Twitter Market Uncertainty Index-ENG, Twitter Economic Uncertainty Index-ENG, and US daily news-based Economic Policy. The sample period is from 07 April 2016–30 June 2021. The estimations are performed using Wavelet based analytical framework. The results reveal high dynamic co-movement of Twitter based uncertainty indices with Distance-to-Default of FinTech firms. However, there is very little co-movement between economic policy uncertainty and FinTech firms’ stability. The novelty of this work lies in the utilization of National University of Singapore’s Distance-to-Default measure, which is available in daily frequency and capable of performing dynamic data analysis. Our results offer maiden evidence of linkage of default risk and news based uncertainty indices.

Privacy-Preserving Prediction of Postoperative Mortality in Multi-Institutional Data: Development and Usability Study.

To circumvent regulatory barriers that limit medical data exchange due to personal information security concerns, we use homomorphic encryption (HE) technology, enabling computation on encrypted data and enhancing privacy. This study explores whether using HE to integrate encrypted multi-institutional data enhances predictive power in research, focusing on the integration feasibility across institutions and determining the optimal size of hospital data sets for improved prediction models. We used data from 341,007 individuals aged 18 years and older who underwent noncardiac surgeries across 3 medical institutions. The study focused on predicting in-hospital mortality within 30 days postoperatively, using secure logistic regression based on HE as the prediction model. We compared the predictive performance of this model using plaintext data from a single institution against a model using encrypted data from multiple institutions. The predictive model using encrypted data from all 3 institutions exhibited the best performance based on area under the receiver operating characteristic curve (0.941); the model combining Asan Medical Center (AMC) and Seoul National University Hospital (SNUH) data exhibited the best predictive performance based on area under the precision-recall curve (0.132). Both Ewha Womans University Medical Center and SNUH demonstrated improvement in predictive power for their own institutions upon their respective data's addition to the AMC data. Prediction models using multi-institutional data sets processed with HE outperformed those using single-institution data sets, especially when our model adaptation approach was applied, which was further validated on a smaller host hospital with a limited data set.

Diaphragm-sparing efficacy of subparaneural upper trunk block for arthroscopic shoulder surgery: A randomised controlled trial.

Inter-scalene block (ISB) is associated with an inevitable risk of hemi-diaphragmatic paresis (HDP). To reduce the risk of HDP, an upper trunk block (UTB) has been proposed at the brachial plexus division level. We hypothesised that UTB would be associated with a lower incidence of HDP than ISB while providing sufficient analgesia following arthroscopic shoulder surgery. Randomised controlled trial. A tertiary teaching hospital. Seventy patients aged 20 to 80 years undergoing arthroscopic rotator cuff repair. Ultrasound-guided ISB or UTB was performed with 5 ml 0.75% ropivacaine. The primary outcome was the incidence of complete HDP, assessed by diaphragm excursion using ultrasound, defined as a decrease to 25% or less of baseline or occurrence of paradoxical movement. Postoperative pulmonary function change, pain scores, opioid consumption and pain-related outcomes were the secondary outcomes. The UTB group had a significantly lower incidence of complete HDP than the ISB group [5.9% (2/34) vs. 41.7% (15/36); absolute difference, 35.8%; 95% confidence interval (CI), 17.8 to 53.7%; P < 0.001]. The postblockade decline in pulmonary function was more pronounced in the ISB group than that in the UTB group. The pain score at 1 h postoperatively was not significantly different between the groups (ISB vs. UTB group: median 0 vs. 1; median difference, -1; 95% CI, -2 to 0.5). No significant difference was observed in any other secondary outcomes. UTB was associated with a lower incidence of HDP compared with ISB while providing excellent analgesia in arthroscopic shoulder surgery.

P-479 Teenagers’ experiences and attitudes toward sex and fertility education in Japan

Abstract Study question What are the experiences and attitudes of Japanese teenagers toward sex and fertility education? Summary answer The participants received sex education on different items to different degrees, and 70% evaluated that the sex education they received in school as neutral. What is known already Although many studies have revealed younger people’s experiences of sex education and their knowledge regarding fertility, very few, both domestic and international, have identified teenagers’ experiences and attitudes toward fertility education. Since 2018, content on fertility has been included in supplementary reading books for Japanese upper secondary school students, and from 2023, students have begun to learn about fertility with the ‘Health’ textbook based on the revised national curriculum. Therefore, it is necessary to clarify teenagers’ experiences and attitudes toward learning about fertility in school. Study design, size, duration This was a cross-sectional questionnaire survey study. The target group consisted of students who had just enrolled to university, were 18-19 years old, and graduated from upper secondary high school in March 2023. The survey was conducted between July and August 2023. The study protocol was approved by the Ethics Committee (approval date: 2023. 6.1; approval number: 5-1). Participants/materials, setting, methods In liberal arts classes with approximately 80% or more first-year students, 873 students who agreed to participate in this study answered a Google forms questionnaire. Of these, 759 (86.9 %) met the inclusion criteria and were included in the analysis. We used the questionnaire ‘Teenager’s knowledge and attitudes to fertility’ which includes 25 items on whether students received and learned from sex education. Simple aggregation and chi-squared analyses were performed. Main results and the role of chance Regarding sex, 46.4% of the participants were male, 51.1% female, and 2.5% other. Of the participants, 99.2% had received sex education at school; 21.6% rated it as very good or good, 71.3% rated it as neutral, and 7% rated it as poor or very poor.The sex education content received by over 60% of the participants was related to the following: sexually transmitted infections (98.4%), contraception (92.5%), puberty (94.2%), menstrual cycle (90.7%), ovulation (87.6%), pregnancy (87.1%), and abortion (60.5%). Regarding fertility and related content, few participants received education on these in school: fertility (8.8%), fertility window (0.0%), menopause (18.3%), relationship between fertility and lifestyle (34.5%), endometriosis (8.8%), and PCOS (2.6%). Women learned more about the menstrual cycle in school compared to men (p&amp;lt;.05). This was the only significant gender difference.Outside school, 30% or less of the participants had studied all 25 items, and nearly 40% had never studied any of the items. Moreover, 11 items were studied by significantly few students outside school than in school (p&amp;lt;.01). Limitations, reasons for caution A limitation of this study is that only 18-19 year olds who had just entered a national university in 2023 were targeted. Therefore, caution should be exercised when generalising these results to the general Japanese teenage population. Wider implications of the findings Few teenagers have studied fertility and related topics both inside and outside of school. It is necessary to enhance schoolteachers’ abilities to appropriately educate teenagers about fertility. In addition, it would be effective for teenagers to be provided opportunities to learn about fertility outside school through websites or short movies. Trial registration number non applicable

Student feedback guides the development of a microbiome card game “No Guts No Glory”

Introduction: We frequently associate microbes with infection, rarely expounding on their usefulness and importance to healthy development. For humanity to leverage these microbial “super powers”, learners from all backgrounds need to appreciate their utility and consider how microbes could help solve some of the most critical problems we face. However, learners are frequently uninterested or intimidated by microbiology. The card game “No Guts No Glory” was created to engage students by piquing curiosity and encouraging informal learning to change perceptions and advocate the value of microbes to good health. Methods: Undergraduates from various faculties in the National University of Singapore were invited to play and give feedback on accessibility, engagement and self-reported learning gains. Results: The game was well-received across disciplinary backgrounds with positive feedback (5-point scale) on game mechanics being fun (4.17±0.63), attractive artwork (3.83±1.00) and scientific snippets (3.79±1.04), positive re-playability (3.46±0.84), player engagement for those without foundational knowledge in microbiology (3.63±1.04), and usefulness of knowledge taught (3.54±1.10). Areas for improvement evidenced from feedback included unclear instructions (2.74±0.98), limited content taught (2.76±0.93), not generating interest to attend formal microbiome classes (2.88±1.17) and not prompting lifestyle changes (1.98±1.11). Conclusion: This pilot study provided valuable insights from the target demographic, with concrete ideas on how to improve the educational potential of “No Guts No Glory”. Findings further lay the groundwork for the design of future instruments to objectively quantify learning gains from gameplay.

Predictors of lateral lymph node metastasis and skip metastasis in patients with papillary thyroid microcarcinoma

BackgroundPapillary thyroid microcarcinoma (PTMC) is characterized by its favorable prognosis and potential for active surveillance (AS) as a management option. However, the presence of cervical lymph node (LN) metastasis, especially lateral LN metastasis, significantly impacts management and prognosis. Previous studies have focused on post-surgery risk factors for cervical LN metastasis. This study aims to identify predictors of lateral LN metastasis by analyzing pre-operative ultrasonographic findings alongside clinicopathological factors.MethodsA retrospective review of medical records was conducted for patients with PTMC who underwent surgery at Chonnam National University Hwasun Hospital between 2004 and 2013. This is a case–control study that compares patients with lateral LN metastasis (N1b) to age- and sex-matched patients without LN metastasis (N0). Subgroup analysis was performed to evaluate risk factors of skip metastasis.ResultsThe study included 90 patients with PTMC with lateral LN metastasis (N1b) and 268 age- and sex-matched patients without LN metastasis (N0). The mean age was 49.3 years, and female patients were dominant in both groups. Structural recurrences of 4.4% (4/90) were observed only in the N1b group. The N1b group exhibited a higher frequency of upper lobe tumor location compared to the N0 group (38.9% vs. 16.0%, p &amp;lt; 0.001). There was no significant difference in the locations with the presence of invasion to adjacent organs. A higher proportion of non-parallel shape was observed in the N1b group than the N0 group (80.0% vs. 66.0%, p = 0.013). There were no differences in echogenicity, sonographic feature, margin, and AP diameter of the thyroid gland between the two groups. In multivariate analysis, independent risk factors for lateral LN metastasis included extrathyroidal extension, multiplicity, upper lobe tumor location, and non-parallel shape. Skip metastasis in patients with PTMC was associated with upper lobe tumor location.ConclusionDetailed ultrasound examinations, evaluating tumor location, number, orientation, and the presence of ETE, are crucial in accurately predicting lateral LN metastasis especially when primary tumor was in the upper lobe to avoid missing skip metastasis. These evaluations can help guide the decision between AS and immediate surgery in patients with PTMC.

Source credibility of beauty vloggers and consumer purchases of vegan cosmetics: The mediating role of cognitive and affective attitude

Vegan cosmetics have become more popular among consumers due to increased environmental awareness and health consciousness after the COVID-19 pandemic. This study aims to investigate the influence of beauty vloggers’ credibility on consumers’ purchase intention toward vegan cosmetics. An integrated research model was built based on the source credibility and stimulus-organism-response theory. Data were collected from a questionnaire survey with 382 Vietnamese consumers at the minimum age of 18 who had experience watching beauty vloggers reviewing vegan cosmetics on YouTube. Partial least squares structural equation modeling was applied to analyze the collected data. The results show that the beauty vloggers’ expertise, trustworthiness, and physical attractiveness all positively impact cognitive and affective attitudes, influencing consumers’ purchase intention. Furthermore, these factors positively impact consumers’ intention to purchase vegan cosmetics. Therefore, cognitive and affective attitudes partially mediate the relationship between the beauty vloggers’ credibility and consumers’ purchase intentions. Given that the direct and indirect effects point in the same direction, these mediators are classified as complementary. This study contributes to deeper understanding of consumers’ intention to purchase vegan cosmetics recommended by beauty vloggers. Acknowledgment The authors would like to thank the Posts and Telecommunications Institute of Technology (PTIT) and the International School, Vietnam National University (VNU), Hanoi, Vietnam, for providing research assistance.

Penerapan Metode TOPSIS Terhadap Skala Prioritas Aspirasi Civitas Kampus UKRI

The campus community at the National University of the Republic of Indonesia has a fairly high level of criticism of the development of the campus itself, however, it turns out that the campus does not have sufficient media to accommodate the aspirations expressed by the campus community. Aspirations can be conveyed, but with a limited scale and time that also makes it difficult for campuses to make decisions that will later have an impact on the development of the National University of the Republic of Indonesia campus, therefore the TOPSIS method is here to make it easier for campuses to make decisions. The TOPSIS calculation refers to the alternative distances to the positive ideal solution and the negative ideal solution. From the results of calculations that have been normalized, the highest value has the right to get priority as the best solution, and conversely, the lowest value is not prioritized to be used as a reference in decision making.

Regional resource provision map: methodology and key approaches

The achievement of sustainable development goals with the help of the implementation of a systematic approach to managing the resource potential of regions through sustainable development goals is one of the actual objectives in regional management. Mapping is known as an approach, which allows combining several data sources with different scaling. This study aims to develop regional resource provision map for creating sustainable development conditions. Multidisciplinary research is a valuable source of this research that allows to unit ESG criteria and their regional commitment through cartographic science tools. The methodology is presented in the form of a sequence of actions to draw up a resource supply map. Using the presented map of Western Kazakhstani region confirms the validity of the scientific and applied methodology. The research outcomes contain proven arguments for the further research based on the issues of constructing integrated resource provision maps for the Kazakhstani regions. Key cartography approaches make it possible to form recommendations for similar maps use in terms of decision-making based on interregional interaction, taking into account resource potential, consisting of natural, labor, financial, and infrastructural capabilities of the regions and environmental risk assessments. Developed recommendations were tested with the help of Microsoft Power BI and SuperMap (laboratory of “Geoinformation Cartography” of Kazakh National University named after al-Farabi Kazakh).

CFD Analysis of Gas-Dynamic and Heat Transfer Processes in a Propulsion System Using Polymer Fuel

In the presented work, a computer model of thermodynamic and gas-dynamic processes in a rocket engine of a new type, which uses solid polymers as fuel is considered. The design feature is the presence of a central body - a gasification chamber, where solid polymer fuel is decomposed into volatiles. To conduct the research, a preliminary thermodynamic analysis of the combustion of gasification products was carried out. Based on the results of the thermodynamic analysis using the mathematical model of the turbulent flow of viscous compressible gas, the processes of gas dynamics and heat transfer in the chamber and nozzle of the rocket engine were simulated. Analyses are made for the geometry of a real experimental sample of a polymer-fueled rocket engine developed at Oles Honchar Dnipro National University (Ukraine), which has passed the first successful tests. As a result of CFD simulation, dynamic and thermal fields in the combustion chamber and engine nozzle were obtained, and ways of further improvement of the design were determined.

COMPORTAMIENTO SECULAR EN LOS DATOS GEOMAGNÉTICOS DE LOS OBSERVATORIOS PERMANENTES DE ARGENTINA

The secular variation of the geomagnetic field is the temporal variation that takes place in the field on time scales between few years to hundreds or thousands of years. On the other hand, impulses or ”geomagnetic jerks” indicate a rapid change in the slope of the secular variation. The origin of these phenomena is linked to the behavior of the geodynamo and the contribution of the outer mantle-core interaction.ROMP (acronym from spanish “ Red de Observatorios Magnéticos Permanentes”) is composed by the following observatories: ”Las Acacias ”(LAS) at Buenos Aires,” Trelew ”(TRW) at Chubut,” Pilar ”(PIL) at Córdoba and ”Orcadas”(ORC) at the Argentine sector in Antartic; the first two depend on the National University of La Plata and the latter on the National Meteorological Service. In the present work one analyzes the secular variation and the determination of jerks in the geomagnetic elements recorded at the ROMP stations, in historical times up to the present.
