Abstract

Instagram is a social media that can be used to promote schools by sharing various documentation of school activities, but schools still have difficulty analyzing engagement to find out the audience's interests. This software development aims to identify topics from captions and analyze the like engagement of each topic. 3,900 caption data were collected from five school Instagram accounts in Palembang with Instaloader. The hLDA algorithm is implemented to identify topics from the caption data, and generate a new dataset that gives the topic information of each caption. This dataset was then classified using SVM and SVM-SMOTE. SMOTE is used to overcome class imbalance in order to improve classification results. In the classification process, the dataset is divided into 70% for training and 30% for testing, with evaluation based on F1-Score. The best results were obtained by SVM-SMOTE, with the best F1-Score value from hLDA 3 Level Dataset (13 labels), reaching 95.68% and the lowest value from hLDA 5 Level Dataset (8 labels), reaching 79.43%. Datasets that have more topics give better classification results. Based on the number of likes for each topic in the hLDA 3 Level Dataset, the most popular topic is topic 11, which includes school facilities, student uniforms, and entertainment events. This information can help schools further develop the most liked topics and improve the less liked topics.

Abstract

Acute disseminated encephalomyelitis (ADEM) is an acute neurological disorder characterized by demyelination of the central nervous system (CNS). It can affect individuals of all ages, more commonly observed in boys with prior viral or bacterial infections and immunizations. ADEM typically presents with an acute and monophasic course of polyfocal neurological deficits. There are no specific symptoms in ADEM, clinical manifestations are based on the site of demyelination. Diagnosis relies on exclusion criteria as there is no definitive marker for diagnosing ADEM.

Abstract

Introduction: Geographic atrophy (GA) is an advanced form of dry age-related macular degeneration (AMD) that can cause severe central vision loss if its progression extends to the foveal area. Currently, therapeutic options for GA remain limited, with safety profiles requiring further evaluation. Lutein and zeaxanthin, as the main components of the Age-Related Eye Disease Study (AREDS2) formula, have become the focus of current research. Both are antioxidants concentrated in the macula, which exert protective effects on retinal structures and reduce oxidative stress. This systematic review aims to evaluate the effectiveness of oral lutein and zeaxanthin supplementation on GA progression and visual acuity in AMD patients. Methods: Literature searches were conducted across four biomedical databases based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. A total of four studies met the inclusion criteria and were analyzed qualitatively. Results: The analysis showed that oral supplementation of lutein (10 mg/day) and zeaxanthin (2 mg/day) may reduce the progression of non-central GA and stabilize or improve visual acuity in patients with AMD. Lutein at doses of 10 mg and 20 mg demonstrated similar effectiveness in improving visual acuity through an increase in macular pigment optical density (MPOD). Conclusion: Based on the findings of this systematic review, oral supplementation with lutein (10 mg/day) and zeaxanthin (2 mg/day), as incorporated in the AREDS2 formulation, appears to slow the progression of non-central GA and preserve foveal integrity (foveal sparing). Further long-term studies are required to confirm the clinical benefits and long-term safety.
