Published: February 2025

У матеріалах статті наведено результати дослідження, що є перспективним напрямом у побудові високолінійних аналогових пристроїв для систем вимірювання, реєстрації та обробки сигналів біомедичних застосувань для використання двотактних структур. Незважаючи на різноманітність існуючих моделей високолінійних пристроїв виробництва провідних всесвітньо відомих компаній, зокрема, Analog Devices, National Semiconductor, Texas Instruments, Linear Technology, ON Semiconductor, Philips, Inetrsil, існують можливості подальшого вдосконалення їх характеристик. У роботі аналізуються кола первинного перетворення високочутливих диференційних сенсорів температури на транзисторних структурах та визначаються оптимальні режими роботи диференційних транзисторних каскадів сенсорів різницевої температури для пристроїв біомедичного призначення. Розробники аналого-цифрових систем часто стикаються з проблемою вибору підсилювача, що працює з малими похибками передачі постійного рівня. Проблема узгодження сигналів також залишається в центрі уваги розробників, оскільки в сучасних ЦАП як ВАХ використовується схема комутації ОА, а для ЦАП з виходом напруги VB і VVC використовуються схеми комутації. Ефективним підходом до побудови подібних аналогових пристроїв є використання трансімпедансних підсилювачів. Вони поєднують в собі як високі лінійні параметри постійного струму, так і ефективні характеристики змінного посилення сигналу. Поряд з освоєнням нових мікроелектронних технологій виготовлення теплових сенсорів потоку, зокрема на основі MEMs-структур, подальший розвиток цих сенсорів для задач медичної діагностики є перспективним і розв’язує задачу підвищення ефективності параметрів сигнальних перетворювачів.

Investigating the Adoption of Metaverse-Based Immersive Learning in TESOL
Authors: Wardat Saja , Akour Mohammed 
Published: February 2025

This study investigates the adoption of Metaverse-based immersive learning in Teaching English to Speakers of Other Languages (TESOL), an area that has been understudied and lacks an understanding of factors influencing the acceptance of this digital platform. In contrast to traditional mobile or e-learning, the Metaverse facilitates all sorts of unique immersive experiences including virtual simulations and cultural dialogues that can aid your process for language acquisition and cultural understanding. However, its reception in the field of TESOL is yet to be substantiated through empirical evidence. The present study explores the effects of constructs such as Perceived ease of use (PEU), Perceived usefulness (PUS), Attitude (ATT), Subjective norm (SBN) and Perceived behavioural control (PBC) on students' Intention to Use Metaverse (IUM) in TESOL context. Data collected from 736 university students in Jordan were analyzed using structural equation modelling (SEM) with a combined Technology Acceptance Model (TAM) and Theory of Planned Behavior (TPB) framework. Results indicate that in terms of direct effects, PEU strongly influences ATT (β = 0.566) and SBN (β = 0.448), whereas PUS regulates ATT (β = 0.514) and SBN (β= 0.482). Path coefficients for the predictive factors of IUM—ATT, SBN, and PBC were 0.326, 0.641, and 0.516 respectively. A J48 decision tree validated by machine learning was able to predict 91.22% of IUM with good accuracy. The results reveal that Metaverse-based TESOL has gradually become part of student habits despite their limited access to technology. The findings of the study assist in improving TESOL curricula and developing informed policies that recommend immersive language learning. Doi: 10.28991/ESJ-2024-SIED1-023 Full Text: PDF

Published: February 2025

Some Asteraceae plants have phytochemicals that are commonly used to treat some illness. However, research on the use of Asteraceae plants as tyrosinase inhibitor agents is still rare. Therefore, this study aims to select the most active fraction of Asteraceae species as tyrosinase inhibitors and suspect active compounds that play a role in it. About 12 species from Asteraceae are extracted using water. The resulting filtrate is partially fractionated using chloroform to obtain water extracts, water fractions, and chloroform fractions. Each extract and fraction of each plant determined the activity of its tyrosinase inhibitor using a microplate reader (ELISA) with L-DOPA as the substrate. Thitonia diversipholia water fraction provided the best activity of all the samples tested with the smallest IC50. The active compounds contained are analyzed using LC-MS / MS. Compounds that act as tyrosinase inhibitors are alkaloid group that dominate the plant, namely trigonelline.

Authors: Pratiwi Rossi Aulia , Ekayanti Ikeu , Palupi Eny 
Published: February 2025

Stunting remains a major malnutrition problem in Indonesia, and is caused by chronic malnutrition and recurrent infections. In 2022, the SSGI reported that Aceh ranked fifth with a high prevalence of stunting (>30%). Malnutrition during the golden period (toddlers) can be corrected. This study analyzed the factors that influence stunting and the most dominant factors in children aged 6-24 months in the Samadua District, South Aceh Regency. This study was conducted using a cross-sectional design. Participants were 120 children under five years of age conducted in Samadua District by simple random sampling from November 2023 to January 2024. Data were collected through interviews, using questionnaires, anthropometric measurements, and recall. Statistical applications were used for data processing. Bivariate data analysis was performed using binary logistic regression test with p<0,25 criteria and multivariate analysis was continued using logistic regression test on influential variables in bivariate analysis and 95% confidence interval (CI). Conclusion: Risk factors affecting stunting in children aged 6-24 months in Samadua District, South Aceh Regency, were birth length (OR=13,000), birth weight (OR=15,400), maternal anemia history (OR=18, 000), ANC history (OR=20,429), ARI frequency (OR=7,500), protein adequacy (OR=5,910), fat (OR = 7,083), calcium (OR = 6,081), iron (OR = 4,375), and zinc (OR = 5,500) intakes.

Authors: Hermilasari Rista Dwi 
Published: February 2025

Background: A pregnancy complication accompanied by hypertension and proteinuria as a cause of maternal morbidity and mortality is preeclampsia. Vitamin D deficiency in pregnant women can cause adverse pregnancy outcomes. Vitamin D is an important micronutrient during pregnancy that potentially prevent preeclampsia.Objectives: The purpose of this review is to evaluate the effect of vitamin D supplementation in preventing preeclampsia.Methods: This narrative literature review is using article tracer from Google Scholar and PubMed database with publication in last ten years. This article search is using keywords “vitamin D”, “hypovitaminosis D”, “pre-eclampsia”, “preeclampsia in pregnancy”, and “vitamin D supplementation”. The data collection technique used a narrative review of six literature regarding the effectiveness of vitamin D in preventing preeclampsia. Research data analysis includes creating research questions, searching articles according to keywords on inclusion criteria, reviewing abstracts and literature content, and reviewing document results.Results: Vitamin D deficiency contributes to the development of preeclampsia. Several studies have found that the incidence of preeclampsia increases in pregnant women with vitamin D deficiency. Serum vitamin D levels in pregnant women with preeclampsia are lower than in pregnant women without preeclampsia. Vitamin D supplementation is effective to rise vitamin D blood concentrations and can also lowering the risk of preeclampsia.Conclusion: Vitamin D supplement proves beneficial throughout pregnancy as an adjuvant therapy for reducing the incidence of preeclampsia.

Higher pre-operative non-invasive fibrosis scores are not associated with surgical outcomes in patients with MASLD undergoing metabolic and bariatric surgery
Authors: Huynh Louis , Kouzmina Ekaterina , Zevin Boris , Flemming Jennifer A. 
Published: February 2025

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of cirrhosis in Canada. Metabolic and bariatric surgery (MBS) leads to histologic improvement in patients with MASLD and obesity; however, patients with advanced fibrosis may be at risk for decompensation in liver function following MBS. There are currently no Canadian data evaluating the association between pre-operative advanced fibrosis and post-operative complications among patients with obesity undergoing MBS. Methods: We conducted a single-centre retrospective cohort study of individuals undergoing primary MBS (Roux-en-Y gastric bypass and sleeve gastrectomy) between September 2016 and August 2021. The primary exposure was pre-operative NAFLD (non-alcoholic fatty liver disease) fibrosis score (NFS). Outcomes of interest included post-operative complications and health care utilization at 30 and 90 days, and weight loss at 30 days post-operatively. Results: After exclusions, 204 patients who received MBS and had the data required to calculate NFS were included. The median age was 46 years (interquartile range 38–55 years) and 181 (89%) were female. A total of 55 (27%) patients had NFS, suggesting advanced fibrosis. There was no significant difference in 30- or 90-day complications and health care utilization rates in patients with higher NFS. Conclusions: Patients undergoing MBS have a high prevalence of steatosis and advanced fibrosis based on the NFS. Our data suggest that higher NFS is not associated with higher short-term post-operative complications in patients undergoing MBS. Further work needs to be done to determine the optimal method of screening for advanced liver disease in patients living with severe obesity.
Canadian military members’ experiences of using programs and services to support upcoming release: A qualitative study
Authors: Tam-Seto Linna , Williams Ashley , Hill Shannon , Ritchie Kimberly , Cramm Heidi 
Published: February 2025

LAY SUMMARY Transitioning from military to civilian life starts with the decision to leave military service, leading to a unique journey for each person. This study looks at how Canadian Armed Forces (CAF) members use various support programs during this transition. These programs are provided by the CAF, Department of National Defence (DND), Veterans Affairs Canada (VAC), and other civilian organizations. The research is part of a larger study and uses interviews to understand the experiences of CAF members. Data were collected May 2018-January 2019 from 80 participants, including both full-time and part-time service members. The initial findings show that many participants found VAC and DND/CAF programs helpful. However, they also faced challenges, such as dealing with complicated administrative tasks and encountering civilian providers who lacked an understanding of military culture. These insights are important for improving the support available to military members as they transition to civilian life.
Virtual and in-person chronic pain management outcomes: A retrospective observational study
Authors: Hapidou Eleni G. , Tutunjian Anthony , Anthonypillai Jennifer 
Published: February 2025

LAY SUMMARY At the onset of the COVID-19 pandemic and its challenges, there was a lack of accessible health care, including chronic pain management. In hopes of providing care for patients who sought treatment, many services shifted to virtual care, which was still accessible despite the pandemic. Although the problem of accessibility was solved, the effectiveness of a virtual chronic pain management program compared with an established in-person program that has historically provided results needed to be evaluated. This research looked to answer the question of a newly established virtual program’s effectiveness by measuring various pain-related variables in patients who completed the program. No differences were found between the results of a sample of patients who completed the program virtually and the results of those who completed the program in person. This study aligns with new research in the field of virtual chronic pain management. Results show that the virtual program is effective and accessible because of the nature of online care. Moving forward, virtual therapy can be effective in treating chronic pain and may potentially be a key tool in the future of clinical care overall.
Navigating mental health risks among Australian military Veterans: Insights for general practice
Authors: Prevett Andrew , Lâm Jade 
Published: February 2025

LAY SUMMARY This study explores mental health risks among Australian military Veterans, emphasizing the critical role of health care practitioners, particularly general practitioners (GPs), in promptly identifying and effectively managing mental health concerns among this population. Through an analysis of data from 150 injured Veterans, research revealed that individuals with shorter service length, those with lower rank, males who underwent voluntary discharge, and females who experienced involuntary medical discharge are at heightened risk of developing a service-related mental health condition. The study highlights the urgent need for early intervention, as Veterans often delay seeking help for their service-related injuries until they reach a crisis point, long after service has ended. Despite Veterans regularly relying on GP services, many GPs lack awareness of the Veterans in their practice and the unique challenges they experience. Educating GPs about specific mental health risk factors related to service is imperative to facilitate early diagnosis and treatment. The study recommends establishing financial incentives to encourage GPs to develop the necessary military cultural competence and integrating relevant content into university curricula.
