Published: December 2024

Abstract

Background:
The initial assessment of trauma is a time-consuming and challenging task. The purpose of this research is to examine the diagnostic effectiveness and usefulness of machine learning models paired with radiomics features to identify blunt traumatic liver injury in abdominal computed tomography (CT) images.

Materials and Methods:
In this study, 600 CT scan images of people with mild and severe liver damage due to trauma and healthy people were collected from the Kaggle dataset. The axial images were segmented by an experienced radiologist, and radiomics features were extracted from each region of interest. Initially, 30 machine learning models were implemented, and finally, three machine learning models were selected including Light Gradient-Boosting Machine (LGBM), Ridge Classifier, and Extreme Gradient Boosting (XGBoost), and their performance was examined in more detail.

Results:
The two criteria of precision and specificity of LGBM and XGBoost models in diagnosing mild liver injury were calculated to be 100%. Only 6.00% of cases were misdiagnosed by the LGBM model. The LGBM model achieved 100% sensitivity and 99.00% accuracy in diagnosing severe liver injury. The area under the receiver operating characteristic curve value and precision of this model were also calculated to be 99.00% and 98.00%, respectively.

Conclusion:
The artificial intelligence models used in this study have great potential to improve patient care by assisting radiologists and other physicians in diagnosing and staging trauma-related liver injuries. These models can help prioritize positive studies, allow more rapid evaluation, and identify more severe injuries that may require immediate intervention.

Published: December 2024

Introduction:
Mucoid degeneration of the anterior cruciate ligament (MDACL) is a poorly understood entity. The collection of mucinous material in the substance of anterior cruciate ligament (ACL) produces pain and thus limits motion in the knee. This study involves clinic-radiological presentation of patients with mucoid ACL, arthroscopic de-bulking of ACL and outcomes.

Materials and Methods:
Between September 2021 and October 2022, 24 patients were diagnosed with MDACL. All cases were examined clinically followed by magnetic resonance imaging (MRI) then confirmed by arthroscopy findings and then were sent for histopathology reporting. Clinical data, including pain location, terminal flexion or extension pain, range of motion, Lysholm knee score, and International Knee Documentation Committee score, were assessed pre- and postoperatively. MRI showing an increased signal of the ACL in T1-and T2-weighted images was reported as mucoid degeneration of the ACL by the radiologist. Upon arthroscopy, the ACL had a homogenous, bulbous, hypertrophied, and taut appearance occupying most of the intercondylar notch space. Debulking of the ACL was performed by excision of the degenerated mucoid tissue, leaving behind as much of the intact ACL as possible, and notchplasty helped prevent impingement of the ACL against the roof and lateral wall. Unfortunately, in 4 (16.67%) patients, we had to reconstruct the ligament due to the ACL insufficiency to stabilize the knee.

Results:
Thirteen patients were males (54.17%), and eleven (45.83%) patients were females, with a mean age of 36.7 years for males (range 19–63 years) and 41.7 years for females (range 28–73 years). All patients had pain in deep flexion, with 70.8% (n = 1 7) reporting trivial trauma before the onset of symptoms. On terminal flexion/extension, pain relief was obtained in 19 of 20 knees, ranging from good to excellent. Stability tests for ACL showed a firm endpoint in all. GNRB arthrometer examination revealed a tibial translation comparable to the noninvolved side, and 85% (n = 20) showed good to excellent subjective satisfaction.

Conclusions:
Prior knowledge of the condition with a high suspicion index and careful MRI interpretation can establish the diagnosis preoperatively. They respond well to a judicious arthroscopic debulking of the ACL with or without notchplasty, improving patient satisfaction and function without causing clinical instability in daily activities. However, young patients should be forewarned about the risk of instability, and the necessity of ACL reconstruction in the future.

Published: December 2024

Abstract

Introduction:
Nail disorders comprise approximately 10% of all dermatological conditions. As diagnosis is not always possible by clinical means alone, additional diagnostic procedures may be required at times. Onychoscopy is a valuable aid in enhancing visible nail features and may help in avoiding nail biopsy in unnecessary cases.

Aims and Objective:
The aim of the study was to determine dermoscopic features of various nail disorders and to correlate dermoscopic findings with the clinical picture.

Materials and Methods:
The study was conducted in the outpatient department of dermatology, venereology and leprology using a hand-held self-illuminated Dermlite DL4N dermoscope. Various patients with nail disorders were examined clinically, a dermoscopy of nails (onychoscopy) was done and dermoscopy findings were correlated with clinical diagnosis. The photographic documentation of the clinical, as well as the dermoscopic picture, was done.

Results:
The study included 126 patients with a diagnosis of onychomycosis, psoriasis, lichen planus, eczema, alopecia areata, subungual hematoma and longitudinal melanonychia. The most common onychoscopic finding was onycholysis (92%) with irregular borders (56%) in psoriasis, onycholysis (95%) with spiked pattern (62%) in onychomycosis, longitudinal ridging (62.5%) in lichen planus, uniform-coloured bands in melanonychia, regular pitting (83%) in alopecia areata, brownish discolouration in a subungual hematoma.

Conclusions:
Onychoscopy is a non-invasive, office-based technique applied for a better understanding of nail pathology and to avoid unnecessary investigations. For some diseases, zooming in adds a lot to clinical examination and reveals suggestive features not otherwise visible to the naked eye.
Intralesional corticotherapy for giant orbital capillary hemangioma
Authors: Damasceno Renato Wendell Ferreira 
Published: December 2024

Abstract
This study is a retrospective case report of two patients with giant orbital capillary hemangioma who underwent intralesional corticosteroid therapy with three monthly injections of 1 ml triamcinolone acetonide 20 mg/ml. The first case was a 5-month-old female patient with a reddish tumor in her left eye (OS) since birth. The ophthalmological examination revealed normalcy of ocular motility of the right eye (OD) and complete obstruction of the visual axis of the OS. The second one was a 5-month-old male patient with a reddish tumor in his OD since birth. The ophthalmological examination demonstrated complete obstruction of the visual axis of the OD and normalcy of ocular motility of the OS. Both patients underwent three monthly intralesional injections of 1 ml of triamcinolone acetonide 20 mg/ml in a surgical setting under general anesthesia. Both patients evolved satisfactorily, functionally, and esthetically, within the first 3 months of starting treatment. Full recovery was considered with the absence of amblyopia and anisometropia, the preservation of extrinsic and intrinsic ocular motility, and the absence of mass lesion according to clinical and magnetic resonance imaging findings.

Published: December 2024

The number of high-quality genomes is rapidly increasing across taxa. However, it remains limited for coral reef fish of the Pomacentrid family, with most research focused on anemonefish. Here, we present the first assembly for a Pomacentrid of the genus Chrysiptera. Using PacBio long-read sequencing with 94.5× coverage, the genome of the Sapphire Devil, Chrysiptera cyanea, was assembled and annotated. The final assembly comprises 896 Mb pairs across 91 contigs, with a BUSCO completeness of 97.6%, and 28,173 genes. Comparative analyses with chromosome-scale assemblies of related species identified contig-chromosome correspondences. This genome will be useful as a comparison to study specific adaptations linked to the symbiotic life of closely related anemonefish. Furthermore, C. cyanea is found in most tropical coastal areas of the Indo-West Pacific and could become a model for environmental monitoring. This work will expand coral reef research efforts, highlighting the power of long-read assemblies to retrieve high quality genomes.
Evolución de los Lenguajes Políticos en torno a la Inteligencia Artificial Generativa en la Educación: dinámicas de Poder y Umbrales de Historicidad
Authors: Jiménez-Ocampo Sandro 
Published: December 2024

Desde el 22 de noviembre de 2022, con la liberación de ChatGPT, la inteligencia artificial generativa (GenAI) ha emergido como un tema central en el ámbito educativo. Este artículo explora la evolución de los lenguajes políticos en torno a la GenAI en la educación, analizando las dinámicas de poder y los umbrales de historicidad que han moldeado su desarrollo. A través de una perspectiva de historia crítica conceptual praxeológica, siguiendo las metodologías de Elias Palti y basándose en experiencias docentes, se cuestiona el uso problemático del término "Inteligencia Artificial" y se examinan los presupuestos epistemológicos que subyacen a las interpretaciones dominantes sobre la GenAI en la educación. Se analizan los "tipos ideales" que promueven una visión tecnocéntrica y optimista de la GenAI, como la personalización del aprendizaje, la democratización del acceso y la eficiencia administrativa. El artículo critica estos enfoques por perpetuar desigualdades, profundizar el determinismo tecnológico y minimizar las dimensiones sociales, culturales y éticas de la educación. Además, se exploran los procesos de dominación y las relaciones de saber-poder asociados con la implementación de la GenAI, destacando la dependencia tecnológica, la dominación epistémica y la vigilancia sobre estudiantes y docentes. Finalmente, se aboga por la necesidad de promover narrativas de soberanía digital y autodeterminación tecnológica, especialmente en el sur global, para desarrollar soluciones tecnológicas que respondan a contextos locales y fomentar un debate más crítico y pluralista sobre el papel de la IA en la educación.

Published: December 2024

Objective: The priority ticket and request for charge are crucial services and activities in any organization that must be considered based on their significance.

Theoretical Framework: Information technology management (ITM) is the process of supervising and controlling an organization's information technology systems, which includes software, hardware, and network, with the goal of improving the effectiveness of information systems.

Method: This study utilized four Artificial Intelligence techniques: multilayer perceptron, decision tree, K closest neighbor, and random forest. Next, we utilized the dataset obtained from the Kaggle website that pertains to the ITM field.

Results and Discussion: The findings indicated that the Random Forest (RF) and Decision Tree (DT) algorithms exhibited superior performance in the initial experiment, however all algorithms yielded identical results in the subsequent experiment.

Research Implications: We proceed by addressing missing values, transforming feature types into appropriate formats, and standardizing the data. Additionally, we employed four assessment metrics to evaluate the performance of the algorithms: accuracy, f1-score, recall, and precision. Lastly, we conducted two experiments: the first one will include predicting priority tickets, while the second one will focus on anticipating requests for charges.

Originality/Value: This paper applied four Artificial Intelligence techniques: random forest, decision tree, K nearest neighbor, and multilayer perceptron. Then, we obtained the dataset from the Kaggle website related to the ITM field and applied three preprocessing steps: filling in missing values, converting types of features from categorical features to numerical features, and scaling the data.

Objective: Produce digital skills-based entrepreneurship learning designs and implementation procedures to support quality education in achieving the Sustainable Development Goals (SDGs).

Theoretical Framework: This study is based on Joyce and Weil's theory of learning design, a method or procedure in helping students to obtain information, ideas, skills and provide training in how to think and learn. The learning design development process uses the ADDIE development model, so the framework in this study is divided into five stages, namely Analysis, Design, Development, Implementation, Evaluation.

Method: This research is a type of educational development research. The development model used is ADDIE. Data collection techniques use observation, interviews, questionnaires, and reviewing relevant theories and research. Data analysis techniques use qualitative descriptive analysis. The sample as the object of research is vocational high school students in East Java Province, Indonesia using the random sampling method.

Results and Discussion: The successfully developed digital skills-based learning design is divided into four main components, namely: (1) Characteristics of entrepreneurial learning; (2) Entrepreneurial learning system; (3) Character of entrepreneurial learning; and (4) Digital skills. The implementation procedure for this learning design involves collaboration between: (1) Entrepreneurship teachers; (2) Productive of expertise competencies teachers; (3) Informatics/computer teachers; and (4) Guidance and counseling teachers.

Research Implications: The results of this study are an alternative for entrepreneurship teachers in vocational high schools in choosing learning designs. Based on the implementation procedure, it provides recommendations to school leaders that entrepreneurial activities are not only the responsibility of entrepreneurship teachers. Entrepreneurial activities will be optimal if there is collaboration between teachers.

Originality/Value: The learning design is developed based on the needs of students to have the skills to use digital devices (hardware and software) in entrepreneurial activities. This condition is in accordance with the demands of student competence in the twenty-first century learning system and the era of the industrial revolution 4.0.

Design of a Novel 31.5 THz Bandwidth Hybrid TDFA-HDFA at 2000 nm and Its Applications in Unregenerated DWDM Lightwave Transmission Systems
Authors: Tench Robert E. 
Published: December 2024

We report the design and applications of a novel multi-Watt (>1Watt output power) 2000 nm band hybrid Thulium- and Holmium-doped fiber amplifier with record wideband 380 nm (31.5 THz) continuously operating bandwidth from 1720 to 2100 nm. We outline the theory, physics, and simulations behind this design and show by comparison with previously published experimental results that the design presented is accurate to within ±0.5 dB in saturated output power and ±1.0 dB in small signal gain. Applications in future ∼300–400 nm bandwidth wideband 2000 nm Pb/s DWDM lightwave fiber optical transmission systems spanning 10,000 km using new hollow-core fiber designs are discussed. In particular, we demonstrate robust beginning-of-life optical signal-to-noise ratio and Q-factor margins for designs of 0.161 Pb/s DWDM unregenerated (without optical-to-electrical-to-optical or O-E-O electronic functions) all-optical transmission in the 2000 nm band over 10,000 km for representative terrestrial and submarine lightwave applications. We achieve a total capacity × distance product of 1608 Pb/s. km (1.61 Exabits/s. km) over a single one-core optical fiber for the 10,000 km system designs. Applications to designs of 40,000 km deployable unregenerated all-optical DWDM 0.124 Pb/s subsea lightwave transmission systems with 5.21 Exabit/s. km capacity ×distance product are outlined.
