Authors: Artymiak Paulina , Żegleń Magdalena , Kryst Łukasz
Published: January 2025

Study aim: To assess changes in body composition, specifically focusing on muscle mass and adipose tissue, among adolescents aged 11–15 in Kraków during the COVID-19 pandemic.
Materials and Methods: Cross-sectional studies were conducted in four selected districts of the city of Kraków in the years 2020 and 2022 (before and after the COVID-19 pandemic). The study group included adolescents aged 11–15 years. The percentage of body fat (%BF) was measured using the bioimpedance method. Additionally, measurements of height, arm circumference, and skinfold thickness of triceps were taken using a skinfold calliper. The collected data were used to calculate the Corrected Arm Muscle Area (CAMA). The normality of the distribution of each feature was assessed using the Shapiro-Wilk test. Statistical analysis was performed to compare differences between groups using two-way ANOVA with Tukey’s HSD post-hoc test or the Kruskal-Wallis test.
Results: Among girls, a decrease in muscle mass was observed in most age categories. The opposite trend was observed among boys, as an increase in muscle mass was observed in most of the age groups. Girls were characterized by a decrease in the %BF in all cohorts, while in boys, an increase in the %BF was observed among 11,13 and 15-year-olds. In most age groups, there was an increase in the average muscle mass and increase in the %BF depending on BMI (Body Mass Index) categories in both sexes.
Conclusions: This study found no notable variances in muscle mass and %BF within the examined group amid the COVID-19 pandemic. While certain outcomes indicated regression, possibly linked to reduced physical activity or prolonged sedentary periods, not all research findings exhibited decline. This could be attributed to online physical activity or enhanced dietary habits.
Exploring Lupins in China: Insights into Cultivation and Challenges for Sustainable Agricultural Development: A Review
Authors: LIM Se-Jung
Published: January 2025

Lupin beans, a nutritious legume, are gaining popularity as a sustainable alternative protein source for both humans and animals, offering potential benefits over traditional options like soybeans. This review paper aims to provide a comprehensive overview of the present status of lupin cultivation, production and research in China. Through a systematic examination of recent literature, we analyze the cultivation practices, production trends and advancements in lupin research within the Chinese context. Lupins, originating from the Mediterranean region, exhibit diverse species distributed across various continents. While historically cultivated primarily for forage lupins have gained traction globally due to their adaptability to different climates and soil types. China is a big importer of lupins, but they are also trying to grow them domestically. This has been challenging due to factors such as the suitability of the local climate and soil and the management of diseases. In China, research is being conducted to improve lupin cultivation by studying genetic traits, disease resistance and soil adaptation. As lupins are known for their nutritional and environmental benefits, China’s agricultural sector is expected to increase production.

Authors: Dogan Gizem Karagoz , Toptanci Ismet Rezani
Published: January 2025

Background: Endodontic infections frequently occur in children and stand out as dental issues where antibiotics are widely favored. However, the recent overuse of antibiotics has resulted in the development of antimicrobial resistance in children. The awareness and understanding dental students have regarding the application of antibiotics for treating endodontic infections in pediatric patients have been explored in limited studies. Purpose: This study aims to evaluate the understanding of fourth- and fifth-year dentistry students—who are actively involved in patient care during their internships and will soon become medical professionals—about prescribing antibiotics to treat endodontic infections. Methods: This study was conducted using the Google Form electronic survey method on intern students at three different faculties of dentistry who have started their clinical internships. Results: Data were obtained from 468 participants who responded to the survey within the scope of the study. Statistically significant differences were observed in terms of knowledge level between those who were informed and those who were not about general antibiotic knowledge, prescription awareness, pediatric antibiotics dose calculations, and parenteral antibiotic applications, as well as between the places where they were informed; the same difference was observed between those who considered the information they received sufficient and those who did not (p < 0.05). Conclusion: The results of the study indicate that dental students have inadequate knowledge about the use of antibiotics in children with endodontic infections. Nevertheless, the study concludes that the knowledge level of the students can be improved through various training and educational programs.

Authors: Saleh Hajar M. , Al-Noori Ammar Kh.
Published: January 2025

Background: Complete tooth loss reduces a patient’s quality of life. The most suitable treatment option is complete denture fabrication, which provides an acrylic-based removable prosthesis as a substitute for all dentition and related structures. Purpose: This study aims to evaluate the shear bond strength (SBS) of three types of artificial teeth—acrylic, composite, and computer-aided design and computer-aided manufacturing (CAD/CAM) milled denture teeth—and the effects of three surface treatments: bur roughening, air abrasion (AB), and dichloromethane (DCM). Methods: Milled CAD/CAM denture base resin was used to test three types of denture teeth: acrylic, composite, and milled CAD/CAM. A total of 120 maxillary right central incisors were used, with 40 of each tooth type. Each type was divided into four groups based on the treatment surface: control (no treatment), AB, bur roughening, and DCM. Universal testing equipment was used to measure SBS. Data were statistically analyzed using ANOVA, and Duncan’s multiple range test was applied to compare mean values among groups. Results: Acrylic and CAD/CAM milled teeth demonstrated higher SBS compared with composite teeth. Teeth treated with AB and DCM surface treatments exhibited increased SBS across all tooth types compared with the control groups. Conclusion: Acrylic and CAD/CAM milled teeth show superior SBS compared with composite teeth. AB and DCM treatments effectively enhance SBS in all types of teeth.
Improperly diagnosed odontogenic myxoma in a 23-year-old female: A radiographic analysis
Authors: Sugianto Gabriel Maria Ferdilia , Nurrachman Aga Satria , Astuti Eha Renwi
Published: January 2025

Background: Misdiagnosis can occur due to various radiographic alterations linked to odontogenic myxoma (OM). Regular examination can detect abnormalities early on, but not all practitioners are aware that these lesions exist. Purpose: This case report aims to describe and discuss an OM case from the perspective of oral radiology on panoramic radiographs and cone-beam computed tomography (CBCT). Case: A 23-year-old female went to her first dentist for orthodontic treatment with no prior radiographic evaluation. On January 7th, 2022, the second dentist extracted teeth 38 and 48 using the panoramic radiograph without identifying lesions. Concerned about swelling on her lower right gingiva, which had gradually grown, the patient went to an oral and maxillofacial surgeon on November 15th, 2022. The clinical examination revealed facial asymmetry with a thick, palpable, firm mass with an ambiguous boundary. Despite the evident movement of tooth 47, the gingiva exhibited no noticeable change in coloration. Case management: From the panoramic examination, multilocular radiolucency with radiopaque septa and aggressive mass characteristics were found. Advanced imaging CBCT was used to investigate further and correlate histology findings for treatment. Conclusion: Odontogenic myxoma is difficult to distinguish from other benign and malignant neoplasms due to the wide variations of radiological patterns. Cone-beam computed tomography provides a thorough and broad range of data that can be used to make a precise diagnosis and develop an effective treatment strategy. This highlights the critical need for a trained expert to thoroughly examine CBCT scans.

Scanning electron microscopy (SEM) has been widely utilized in the field of materials science due to its significant advantages, such as large depth of field, wide field of view, and excellent stereoscopic imaging. However, at high magnification, the limited imaging range in SEM cannot cover all the possible inhomogeneous microstructures. In this research, we propose a novel approach for generating high-resolution SEM images across multiple scales, enabling a single image to capture physical dimensions at the centimeter level while preserving submicron-level details. We adopted the SEM imaging on the AlCoCrFeNi2.1 eutectic high entropy alloy as an example. SEM videos and image stitching are combined to fulfill this goal, and the video-extracted low-definition images are clarified by a well-trained denoising model. Furthermore, we segment the macroscopic image of the eutectic high entropy alloy, and the area of various microstructures is distinguished. By combining the segmentation results and hardness experiments, we found that the hardness is positively correlated with the content of the body-centered cubic phase and negatively correlated with the lamella width. The whole procedure is also applied to a thermoelectric gradient material (PbSe-SrSe). Our work provides a feasible solution to generate macroscopic images based on SEM for further analysis of the correlations between the microstructures and spatial distribution, and can be widely applied to other types of microscopes.

Pa'au Village is one of the villages in the Meratus Mountains which is inhabited by the Banjar people who still have descendants from the Dayak Kayutangi tribe. The people in Pa'au Village are very dependent on the forest, on average their livelihoods are farmers, farm labourers. by utilizing the forest for farming, gardening and hunting. The importance of forests for socio-economic life is increasingly recognized, because cultural values in the form of human wisdom in managing nature are considered the best way to manage nature. This study aims to explore the infrastructure aspects of local community wisdom in forest management in Pa'au Village. Data collection was carried out through field observations and interviews. Respondents were identified through a purposeful sampling method. Data processing is carried out through inductive qualitative analysis, which can provide a thorough and thorough understanding of the actual situation. Based on the findings of a study on the wisdom of the local community in forest management in Pa'au Village, the people in farming use the "turn-back" pattern of cultivation as well as the Dayak people who inhabit the Meratus mountains in general. Traditions or rituals are still carried out by the people who live in Pa'au Village, but not all activities carried out are accompanied by rituals. Communities take advantage of land that they consider to be no longer productive with forest gardening.Desa Pa'au merupakan salah satu desa yang berada di Pegunungan Meratus yang dihuni oleh masyarakat suku Banjar yang masih memiliki keturunan dari suku Dayak Kayutangi, Masyarakat di Desa Pa’au sangat bergantung pada hutan, rata-rata mata pencaharian mereka adalah petani, buruh tani dengan memanfaatkan hutan untuk berladang, berkebun dan berburu. Pentingnya hutan bagi kehidupan sosial ekonomi semakin diakui, karena nilai-nilai budaya berupa kearifan manusia dalam mengelola alam dianggap sebagai cara terbaik untuk mengelola alam. Penelitian ini bertujuan untuk menggali aspek infrastruktur material pada kearifan lokal masyarakat dalam pengelolaan hutan di Desa Pa'au. Pengumpulan data dilakukan melalui observasi lapangan dan wawancara. Responden diidentifikasi melalui metode purposive sampling. Pengolahan data dilakukan melalui analisis kualitatif induktif, yang dapat memberikan pemahaman yang menyeluruh dan komprehensif tentang keadaan yang sebenarnya. Berdasarkan temuan kajian infrastruktur material pada kearifan lokal masyarakat dalam pengelolaan hutan di Desa Pa'au, masyarakat dalam berladang menggunakan pola perladangan “gilir balik” sama halnya dengan masyarakat suku Dayak yang mendiami pegunungan meratus pada umumnya. Tradisi atau ritual masih dilakukan oleh masyarakat yang tinggal di Desa Pa'au, namun tidak semua kegiatan yang dilakukan diiringi dengan ritual.

The Centers for Medicare & Medicaid Services (CMS) recently introduced mandatory reporting of patient-reported outcomes (PROs) following primary, elective total joint arthroplasty (TJA) procedures. This article explores the implications and implementation challenges of this policy shift in the field of orthopaedic surgery. With a review of the existing literature, we analyze the potential benefits and limitations of PROs, discuss the role of CMS in health-care quality improvement initiatives, explain the predicted difficulties in the successful implementation of this new mandate, and provide recommendations for the successful integration of the reporting of PROs in clinical practice.
Aspirin Is as Effective and Safe as Oral Anticoagulants for Venous Thromboembolism Prophylaxis After Joint Arthroplasty

Published: January 2025

Background:

Joint arthroplasty effectively treats osteoarthritis, providing pain relief and improving function, but postoperative venous thromboembolism (VTE) remains a common complication. This study therefore assessed the effectiveness and safety of aspirin compared with oral anticoagulants (OACs) for VTE prophylaxis after joint arthroplasty.

Methods:

A systematic review and meta-analysis was performed by searching PubMed, Embase, the Web of Science, and the Cochrane Library for randomized controlled trials (RCTs) up to May 14, 2024, that compared the effect of aspirin versus OACs on VTE prophylaxis in adults undergoing joint arthroplasty. Data extraction followed the PRISMA guidelines. Two independent researchers conducted the literature searches and data extraction. A random-effects model was used to estimate effects. The primary outcome was the incidence of VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE); secondary outcomes included bleeding, wound complications, and mortality.

Results:

The meta-analysis included 11 RCTs with a total of 4,717 participants (55.1% female) from several continents. The relative risk (RR) of VTE following joint arthroplasty was 1.11 (95% confidence interval [CI], 0.93 to 1.32) for aspirin compared with OACs. Similar results were observed for DVT (RR, 1.12; 95% CI, 0.90 to 1.40) and PE (RR, 1.18; 95% CI, 0.51 to 2.71). There were no significant differences in the risks of bleeding, wound complications, or mortality between patients receiving aspirin and those receiving OACs. Subgroup analyses considering factors such as study region, type of joint surgery, type of VTE detection, year of publication, use of mechanical VTE prophylaxis, aspirin dose, type of OAC comparator, study quality, and funding also found no significant differences in VTE incidence between aspirin and OACs. The overall quality of evidence for VTE and DVT outcomes was high.

Conclusions:

Based on high-quality evidence from RCTs, aspirin is as effective and safe as OACs in preventing VTE, including DVT and PE, after joint arthroplasty, without increasing complications.

Level of Evidence:

Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.
INDONESIA’S ELECTRONIC MONEY LANDSCAPE: BETWEEN EFFECTIVITY AND INCLUSIVITY
Authors: Mahardika Zahrashafa
Published: January 2025

Technology has transformed payment systems. Regulated digital money transactions are replacing traditional cash transactions. However, policy frameworks on payment systems often neglect to consider the diverse needs of society despite the critical role that payment systems play in society. This can be seen by the increasingly mandatory use of electronic money, which may exclude groups who have relied on traditional cash transactions but have unequal technological access. This paper explores the importance of electronic money accessibility from the perspective of Indonesian court decisions. This study reveals that current implementations, policies, and court decisions regarding electronic money have mainly focused on effectiveness rather than inclusivity. Electronic money was created to help unbaked people access financial services. However, ensuring people have technological access to these services must include everyone. This study recommends that policymakers ensure that electronic money services are accessible to the unbanked and those with limited technology access when promoting their use. On top of that, the government must also reinforce that using rupiah, in any form, remains a legal means of payment and must be respected in all transactions.

El objetivo de la presente investigación fue evaluar la relación de la calidad del agua de las pozas de oxidación y la percepción de la población de Alto Larán (Ica), se evaluó mediante la aplicación de 328 encuestas a pobladores y análisis de datos microbiológicos y fisicoquímicos de las porciones de agua extraídas de las pozas de oxidación. El 90,85% desconoce la problemática, pero el 82,32% ha sentido malestar por olores, atribuyéndolo en un 83,84% a las pozas de oxidación del distrito. Los análisis evidenciaron altas cargas orgánicas y contaminación fecal en el agua, con niveles de sulfuros vinculados a la proliferación de fluidos olorosos, haciendo referencia al sulfuro de hidrógeno. Las comparaciones que se realizaron entre las distancias de las personas encuestadas a las pozas de oxidación y sus creencias sobre sus efectos en salud/calidad de vida, los fastidios a causa de la multiplicación de sustancias olorosas y sobre si ellos creían que las pozas de oxidación es la causante de los malos olores, mostraron un alto porcentaje de influencia de la distancia de la persona encuestada a las pozas de oxidación sobre las respuestas dadas por la población en las encuestas. Se concluye la necesidad de mejorar el sistema de tratamiento de aguas residuales para reducir compuestos causantes de olores desagradables y mitigar el impacto sobre la población cercana. Se recomienda implementar programas de comunicación ambiental y monitoreo participativo de olores.

Objective: The objective of this study was to investigate the current state of insomnia among secondary vocational school students, identify its influencing factors, and explore potential mechanisms of action.
Methods: The study population consisted of 2150 students (968 male and 1182 female) enrolled in a secondary vocational school in Wuhan, China. A cross-sectional research design was employed to analyze the data using descriptive statistics, correlation analysis, structural equation modeling, and bootstrapping.
Results: Adolescents with poorer family functioning, higher levels of paranoid personality traits, and higher levels of anxiety are more likely to experience insomnia. There was a significant direct association between family functioning and insomnia (β = −0.153, p < 0.001). Paranoid personality traits and anxiety were not only significant independent mediators in the relationship between family functioning and insomnia (paranoid personality traits: β = 0.021, 95% CI: [−0.035, −0.008]; anxiety: β= 0.173, 95% CI: [−0.204, −0.114]) but also chain mediators (β = 0.059, 95% CI: [−0.073, −0.048]).
Conclusions: Managing insomnia in secondary vocational school students requires familial and individual strategies, including reducing family conflict, improving family functioning, and addressing cognitive biases and anxiety.

Clean and safe drinking water is a fundamental necessity for human health and well-being and a critical component in sustainable ecosystem development. In recent decades, water quality issues have become even more urgent due to population growth, industrial expansion and climate change.

A series of works by foreign researchers report results obtained by applying neural networks. There are studies confirming results of water quality prediction generated by neural networks to be quite valid.

In this research, we used Google Earth Pro, Microsoft Excel, water flow sensor based on Arduino UNO board with author's modification (tail feathering and built-in plugin for calculation of flow velocity), Python, Tensorflows keras2.2.0, Scikit-learn, Pandas libraries for machine learning and development of neural network architecture. In this study, two ANNs were combined to build a hybrid neural network model for predicting water quality indicators.

Neural network models offer unique opportunities to improve water resources management at various levels, ranging from local to global one. A key advantage of such models is a possibility to adapt them to specific conditions and requirements, which provides more accurate prediction and timely decision making under uncertainty. The relevance of the work is determined by application of neural networks for water quality prediction. This can improve systems for early warning about pollution, help optimize operational processes at water treatment plants and develop effective water management strategies.

In this research, an innovative hybrid neural network model has been developed for predicting water quality indicators. It is based on integrating deep convolutional neural network and bidirectional recurrent neural network, which consists of three functional parts.
