Dynamic Layered Entropic Patterning for Ransomware Detection Using Nonlinear Entropy Clustering Analysis
Authors: Vadom Vincent , Thalberg Lucian , Walker Edward , Havelka Nikolai
Published: November 2024

The rapid evolution of ransomware threats and their increasingly sophisticated evasion tactics present significant challenges for conventional detection mechanisms. Addressing this gap, a novel approach termed Dynamic Layered Entropic Patterning (DLEP) introduces an innovative framework designed to detect ransomware activities through entropy-based clustering of network anomalies. DLEP applies a multi-layered analysis structure that isolates entropy fluctuations specific to ransomware behaviors, distinguishing them from benign system processes and achieving higher detection accuracy across a diverse range of ransomware types. Unlike traditional detection models reliant on static signatures or predefined behavioral markers, DLEP dynamically categorizes entropy variations, adapting to new and previously unknown ransomware without requiring constant updates or recalibration. Experimental results reveal that DLEP not only maintains robust detection accuracy but also minimizes false positive and false negative rates, ensuring reliable performance even when facing advanced encryption techniques employed by modern ransomware variants. Furthermore, DLEP’s modular and computationally efficient design supports scalable deployment, allowing it to operate effectively in high-traffic environments without excessive resource consumption. These findings demonstrate the potential of entropy-focused methodologies to enhance ransomware detection frameworks, highlighting DLEP as a flexible, resource-efficient, and resilient solution to contemporary cybersecurity challenges.
Formation conditions of fresh groundwater deposits in Irkutsk artesian basin
Authors: Kuranicheva A. I.
Published: November 2024

The purpose of the research is to give a detailed description of hydrogeological conditions of the Irkutsk artesian basin, which is a large hydrogeological structure of the second order. The method of morphostructural analysis has been used to distinguish the territories with different formation conditions of fresh groundwater deposits as well as to identify the boundaries of large lowlands and uplands in comparison with the geological structure. To make a generalization, the author uses the data on 45 deposits of fresh drinking groundwater explored on the territory of the Irkutsk artesian basin of the second order with the operational reserves of more than 500 m3/day. Deposits of fresh groundwater in Jurassic terrigenous rocks are confined to large relief elevations within tectonic depressions while the deposits in both Cambrian carbonate and Jurassic-Ordovician terrigenous sediments are confined to tectonic uplifts.The deposits are replenished by natural resources. The production horizons of large deposits in Cambrian and Ordovician rocks are fed by attracted resources. In the lowlands the deposits of fresh groundwater are formed only in Quaternary alluvial deposits, due to infiltration from rivers (attracted resources). Neotectonic movements are the ones that had a dominant influence on the formation of natural resources and dynamic reserves as well as on underground flow localization as they ensured the distribution and localization of surface and underground flow. It is also noted that when identifying promising areas for searching for fresh underground water, it is advisable to rely on the distribution patterns of fresh underground water reserves of already explored deposits within the identified morphostructures.

Introduction. One of the few ways to rehabilitate profound hearing loss in elderly patients is cochlear implantation. A number of studies have been published assessing the effect of unilateral cochlear implantation on cognitive function in elderly patients, but the results have been mixed.

Aim. Evaluation of the impact of unilateral cochlear implantation on auditory and non-auditory functions in elderly patients.

Materials and methods. The study included 50 elderly and senile patients (mean age 67.16 ± 3.5 years). RBANS-H, HI-MoCA tests were used to assess cognitive function. Quality of life, depression and anxiety levels were assessed by HADS, SF-36. Auditory function was assessed by pure tone audiometry, speech audiometry, SSQ, HISQUI19.

Results. The study showed improvement in cognitive function in patients with and without residual hearing. There was also an improvement in quality of life, a decrease in depression and anxiety in both study groups. When assessing the auditory function, statistically significant differences between the study groups remained during the study for the sound quality indicator (SSQ test), while other parameters did not have a statistically significant difference at the end of the study. In addition, the study did not reveal a statistically significant effect of vestibular dysfunction on cognitive function in patients.

Conclusions. Unilateral CI as a method of rehabilitation of profound impairments of auditory function in elderly and senile patients has demonstrated its high effectiveness.

The Syro-Ephraimite War in the Context of Assyrian Trade Interests in the Southern Levant
Authors: Kinowski Krzysztof
Published: November 2024

Dotychczasowe interpretacje tzw. wojny syro-efraimskiej (2 Krl 16,5; Iz 7,1–2; por. 2 Krn 28,5–8) wskazują na elementy natury politycznej tego konfliktu: ekspansyjne dążenia Asyrii, antyasyryjską koalicję Aramu i Izraela, utratę niezależności przez Judę czy negatywny wpływ imperium na religię i kult w Jerozolimie. Nowe odkrycia archeologiczne i adekwatna historyczna kontekstualizacja wydarzeń rzucają nowe światło na naturę tego konfliktu. List z Nimrud 2715 wskazuje na ekonomiczne tło działań militarnych Tiglat-pilesera III w południowym Lewancie w tym okresie (dostęp do morskich szlaków handlowych i nowych kanałów przepływu dóbr). Podobnie wydaje się, że względy ekonomiczne (kontrola nad szlakami handlowymi przez Transjordanię w kierunku Arabii i Egiptu) stały u podłoża konfliktu syro-efraimsko-judzkiego. Perspektywa korzyści ekonomicznych była też motywem wejścia Królestwa Judy w relację wasalną z Asyrią, dając impuls do rozwoju i wzrostu dobrobytu w królestwie, co potwierdzają najnowsze odkrycia archeologiczne. W świetle historycznej rekonstrukcji wydarzeń król Achaz jawi się jako wytrawny strateg i inicjator rozwoju swojego królestwa.
Zmysł węchu w kulturze medialnej
Authors: Kusio Urszula
Published: November 2024

Cel artykułu jest dwojaki. W pierwszej jego części postaram się dowieść, że zmysł węchu od dawna jest obecny w refleksji badawczej i powszechnej świadomości. Dlatego też upowszechniana współcześnie wiedza, że to pandemia COVID-19 w sposób istotny przewartościowała dotychczasowy sposób myślenia o wadze tego zmysłu w życiu człowieka, jest fałszywa. Przekonanie, że dopiero pandemia przyczyniła się do zainteresowania węchem i dostarczyła paliwa do intensywnych badań nad nim nie znajduje potwierdzenia w historii nauki ostatnich dekad.
W drugiej części tekstu zaproponowana zostanie teza, że dotychczasowe starania zaromatyzowania starych i nowych mediów nie należy ujmować w kategoriach porażki. Fiasko polisensoryczności, paradoksalnie, może być jedną z ostatnich ostoi wolności współczesnego uczestnika kultury medialnej.

Imaginaria i złudzenia w epoce internetu i sztucznej inteligencji
Authors: Pleszczyński Jan
Published: November 2024

Współcześnie, gdy sferę intersubiektywności w coraz większym stopniu i w zawrotnym tempie kolonizują media cyfrowe i e-komunikacja, problematyka imaginariów i złudzeń ponownie staje się bardzo istotna. Jeszcze stosunkowo niedawno można było utrzymywać, że zagadnienia z nimi związane są już dostatecznie dobrze rozumiane i znalazły satysfakcjonujące wyjaśnienia. Jednak w epoce internetu i sztucznej inteligencji ukazują się w nowej odsłonie, przypominając o swojej nieprzemijającej aktualności.
Problematykę złudzeń i imaginariów rozpatruję w perspektywie komunikologicznej, koncentrując się na aspektach epistemologicznych. Wskazuję na genealogię imaginariów i złudzeń oraz ich wzajemne powiązania. W prezentowanej przeze mnie koncepcji pierwotnymi generatorami złudzeń są biologiczne aparaty światoobrazu, natomiast imaginaria, jako wytwory kulturowe, są na złudzeniach nadbudowane dzięki komunikacji i mediom komunikacyjnym.
Anti-thrombotic Mechanisms of Echinochrome A on Arterial Thrombosis in Rats: In-Silico, In-Vitro and In-Vivo Studies
Authors: Khalaf Marina Lotfy , Soliman Amel Mahmoud , Fahmy Sohair Ramadan , Mohamed Ayman Saber
Published: November 2024

Background:

Arterial thrombosis is one of the most significant healthcare concerns in
the world. Echinochrome A (Ech-A) is a natural quinone pigment isolated from sea urchins. It has
a variety of medicinal values associated with its antioxidant, anticancer, antiviral, anti-diabetic,
and cardio-protective activities.

Objective:

The current study aims to investigate the effect and mechanism of Ech-A to inhibit
thrombus formation induced by ferric chloride in rats.

Methods:

Twenty-four rats were assigned into four groups (n= 6); sham and thrombotic model
groups were orally administered 2% DMSO, while the other groups were treated with two dosages
of Ech-A (1 and 10 mg/kg, body weight). After seven days of administration, all groups were exposed
to 50% ferric chloride for 10 min, except the sham group exposure to normal saline.

Results:

The molecular docking showed the free binding energies of Ech-A and vitamin K (Vit.
K) with Vit. K epoxide reductase were -8.5 and -9.8 kcal/mol, which confirm the antithrombotic
activity of Ech-A. The oral administration of Ech-A caused a significant increase in partial thromboplastin
time, prothrombin time, clotting time, platelet count, fibrinogen levels, factor VIII, glutathione
reduced, catalase, nitric oxide, and glutathione S-transferase. While white blood cells
count, calcium level, and malondialdehyde concentration significantly decreased. The histological
examination revealed a definite improvement in the carotid and cardiac tissues in the Ech-A
groups.

Conclusion:

The study results showed that Ech-A prevented thrombosis by several mechanisms,
including chelating calcium ions, increasing the NO concentration, suppressing oxidative stress,
and antagonizing Vit. K.
Association between Volunteer Activity Participation and Daily Sedentary Time among Adults in Japan: A Cross-sectional Study
Authors: Ukawa Shigekazu , Kato Yusuke , Lee Yonggeun , Sugiyama Masaaki , Saito Hiroko , Ohara Kazuoki , Mori Kazuhiko
Published: November 2024

Introduction

Sedentary behavior, involving low energy expenditure while sitting or reclining, is linked to health risks. Volunteering may help reduce sedentary time through social interaction and physical activity, but this relationship is understudied in non-Western contexts. This study investigated the association between volunteer activity frequency and daily sitting time among adults in Aichi and Kanagawa Prefectures, Japan, regions with higher aging.

Methods

A cross-sectional study was conducted in two regions of Japan, with a sample of 1,224 adults (585 men and 639 women) from these regions. Data on volunteer activity frequency and daily sitting time were collected using questionnaires. Multiple regression models explored the relationship between volunteer frequency and sitting time, adjusting for confounders.

Results

The mean daily sitting time was 357.66 ± 240.40 minutes. Participants volunteering four or more times weekly reported significantly shorter sitting times compared to non-participants, with an average difference of 131.96 minutes (95% CI: -253.83 to -10.08) in the multivariable-adjusted model. This association was stronger among males (difference: 180.51 minutes; 95% CI: -353.84 to -7.28) and older adults aged ≥65 years (difference of 142.48 minutes; 95% CI: -272.58 to -12.38).

Conclusion

Frequent volunteering is associated with shorter sitting times, particularly among males and older adults. However, due to the cross-sectional design, causal inferences cannot be made, and the associations should be interpreted with caution. Compared to Western populations, sitting time was lower, but it still exceeded public health recommendations. Future research should explore the longitudinal effects and identify specific volunteer activities that promote active lifestyles.

Authors: Kumalasari Ika Dyah , Maulana Muhammad Hanin Thariq
Published: November 2024

Many street food vendors lack an understanding of food safety standards, resulting in cases of poisoning due to microbiological and chemical contamination. One popular snack sold is aci dicolok (cilok). This study aims to analyze microbiological contamination and hazardous chemical additives in cilok and the sauce sold in the Southern Alun-alun of Kraton Yogyakarta. The parameters of this study included calculating the total number of bacteria and salmonella using Plate Count Agar (PCA) and Salmonella Shigella Agar (SSA) media and qualitatively analyzing the content of formaldehyde, borax, and rhodamine B using Easy test brand test kits on cilok and sauce samples from 10 sellers. The results were then compared with the standards of The Indonesian Food and Drug Authority (BPOM) and the Indonesian National Standard (SNI). The results showed that 40% of cilok and 100% of sauce samples exceeded the total bacteria limit of SNI and BPOM (1 x 105 CFU/g). For the total Salmonella content, 10% cilok and 0% sauce samples exceeded the SNI and BPOM salmonella limit (0 CFU/g). The analysis of hazardous chemical additives revealed that 10 samples were negative for formaldehyde and borax, but 10% of the sauce tested positive for rhodamine B. The study results indicate that cilok and sauce are subject to microbiological and chemical contamination, so education and supervision by the authorities are needed for cilok sellers.

Authors: Mahisa Yustira Hanin , Rohmawati Ninna , Antika Ruli Bahyu
Published: November 2024

Stunting is a significant health problem that can affect the growth and development of toddlers. It is measured according to WHO standards using the height-per-age index, with a score below -2 SD indicating stunting. Supplementary feeding is one of the factors influencing stunting in toddlers, and it can be influenced by birth interval and mother’s education level, which in turn influence changes in the child’s nutritional status. This study aimed to analyze the relationship between birth interval and maternal education level with the rate of supplementary feeding in stunted toddlers aged 24-59 months in Cumedak Village, Jember Regency. An observational analytic method with a cross-sectional study design was used, involving 54 respondents of stunting toddlers aged 24-59 months. Data were collected through interviews and a 2x24-hour food recall method. The results show that the supplementary feeding practices were categorized as less (53.7%). A Chi-square statistical test revealed no significant relationship between birth interval and supplementary feeding rate (p = 0.715, p > 0.05), but there was a significant relationship between the mother’s education level and supplementary feeding rate (p = 0.002, p < 0.05). In conclusion, there is no relationship between birth interval and the quality of supplementary feeding, but there is a significant relationship between maternal education level and the quality of supplementary feeding.

Introducción: Las primeras cooperativas en el estado de Oaxaca, México, se fundaron por iniciativa de los trabajadores en el siglo pasado con el propósito de aportar su fuerza de trabajo para crear valor en el mercado del transporte público. Objetivo: Se analiza la doble dimensión en la que se desenvuelve la industria cooperativa del transporte público de pasajeros de la Zona Metropolitana de Oaxaca, la dualidad se resume en un conflicto interno entre racionalidad económica y los objetivos sociales de la cooperativa. Metodología: El estudio se realizó con un enfoque cualitativo, con diseños de la Teoría Fundamentada, los estudios etnográficos y las investigaciones dogmático-jurídicas. Resultados: Se identificaron tres cooperativas creadas por choferes, mecánicos y ayudantes, quienes originalmente laboraban en empresas privadas del transporte. Con el paso del tiempo, los socios cooperativistas fueron sustituidos por socios capitalistas que se apropiaron de las concesiones y trastocaron los principios cooperativos con los que fueron creadas estas empresas. Conclusiones: Las cooperativas del transporte público anteponen el lucro por encima de los principios cooperativos como: la existencia de un gobierno democrático; el mantenimiento de los fondos de reserva, y; la protección de los trabajadores, lo que conduce a la precarización del empleo en la industria.
Kabata Banda & the significance of Islamic eco-theology education
Authors: Latuapo Abdullah , Farid Muhammad
Published: November 2024

The environmental crisis is a real threat to human survival. Climate change, natural disasters, and food crises are some of the devastating impacts that can have a major impact on the human population. The Banda Islands have a wide water zone with diverse marine biota but face the threat of natural disasters from active volcanoes and human behaviour that is not environmentally friendly. Historically, Banda has a tradition that is very close to coastal nature. This is revealed in their traditional song known as Kabata Belang, often sung while rowing a traditional boat (Belang) in various community cultural stages. By adopting phenomenology perspectives, this research is focused on reviewing the narration of the Fiat’ Kabata belang sacrament songs to seek out the implied values of environmental ethics and its urgency in handling coastal environmental problems in Banda Naira today. The results show that Kabata Belang contains both theological and ecological values (eco-theology) apart from being an instrument of traditional rituals. There are 13 stanzas in Fiat village Kabata Belang that are oriented towards maintaining several coastal natural objects, such as mountains, coasts, birds, and fish. The singing of the Kabata Belang as a traditional wisdom functions as an "advisor" for the people of Banda today to preserve the marine and coastal environment. This research recommends the importance of writing down the Kabata text, complete with pictures and articulations that are more accessible to the public as a guidebook, especially for the younger generation to understand better and participate in creative efforts to preserve the coastal and marine environment in their everyday lives.

Authors: Stefany Stella , Helmi Jessica
Published: November 2024

This paper explores the role of the digital literacy of Indonesian educators in their competence regarding online course design, in a Distance Education context, at tertiary level. It focuses on the competence of lecturers regarding digital literacy, and self-perceived ability in designing online courses. Lecturers (n = 275) at both public and private universities in Indonesia participated in this study. The developed instrument, measuring seven elements of digital literacy competence, in a teaching and pedagogical framework (Payton and Hague 2010), and six components of effective course design, aimed at achieving desired learning outcomes for students, was adopted from that of Brown and Voltz (2005). The result of Pearson’s correlation testing indicated a strong relationship between two variables r (275) = .765, p .001. The findings also showed that the digital literacy competence of educators had an influence of 58.6% on the quality of online course design, with a significant impact (F(1)=386.358; p=.000). It may therefore be concluded that it is important to upscale the digital literacy competence of lecturers, to promote the quality of online course design, in order to achieve desired learning outcomes. Further studies should particularly consider measuring the impact of online course design on the quality assurance of the course.

Published: November 2024

Background

Primary health care (PHC) services face operational challenges due to high patient volumes, leading to complex management needs. Patients access services through booked appointments and walk-in visits, with walk-in visits often facing longer waiting times. No-show appointments are significant contributors to inefficiency in PHC operations, which can lead to an estimated 3%-14% revenue loss, disrupt resource allocation, and negatively impact health care quality. Emirates Health Services (EHS) PHC centers handle over 140,000 visits monthly. Baseline data indicate a 21% no-show rate and an average patient wait time exceeding 16 minutes, necessitating an advanced scheduling and resource management system to enhance patient experiences and operational efficiency.

Objective

The objective of this study was to evaluate the impact of an artificial intelligence (AI)-driven solution that was integrated with an interactive real-time data dashboard on reducing no-show appointments and improving patient waiting times at the EHS PHCs.

Methods

This study introduced an innovative AI-based data application to enhance PHC efficiency. Leveraging our electronic health record system, we deployed an AI model with an 86% accuracy rate to predict no-shows by analyzing historical data and categorizing appointments based on no-show risk. The model was integrated with a real-time dashboard to monitor patient journeys and wait times. Clinic coordinators used the dashboard to proactively manage high-risk appointments and optimize resource allocation. The intervention was assessed through a before-and-after comparison of PHC appointment dynamics and wait times, analyzing data from 135,393 appointments (67,429 before implementation and 67,964 after implementation).

Results

Implementation of the AI-powered no-show prediction model resulted in a significant 50.7% reduction in no-show rates (P<.001). The odds ratio for no-shows after implementation was 0.43 (95% CI 0.42-0.45; P<.001), indicating a 57% reduction in the likelihood of no-shows. Additionally, patient wait times decreased by an average of 5.7 minutes overall (P<.001), with some PHCs achieving up to a 50% reduction in wait times.

Conclusions

This project demonstrates that integrating AI with a data analytics platform and an electronic health record systems can significantly improve operational efficiency and patient satisfaction in PHC settings. The AI model enabled daily assessments of wait times and allowed for real-time adjustments, such as reallocating patients to different clinicians, thus reducing wait times and optimizing resource use. These findings illustrate the transformative potential of AI and real-time data analytics in health care delivery.

BACKGROUND

Performance anxiety represents a significant challenge for students, manifesting as a fear of failure and difficulties managing exam-related concerns and academic pressures. According to recent statistics, anxiety affects over 4% of the global population, underscoring the need for effective management methods. Studies indicate that yoga and virtual reality (VR) training can alleviate symptoms of performance anxiety.

OBJECTIVE

Students are significantly affected by performance anxiety. In this trial, virtual reality (VR)-based CBT is compared with yoga interventions to find effective treatments.

METHODS

A single-blinded randomized controlled trial will measure whether the interventions lower students’ performance anxiety. The stratified randomization will be employed to ensure equal distribution regarding baseline anxiety and gender in both groups. Measures: The main outcome is anxiety reduction as measured by STAI-Y1 and STAI-Y2 scales. Other second-order effects are emotional regulation (ER) and quality of life (QoL).

RESULTS

VR-CBT is expected to reduce anxiety very quickly, whereas yoga is predicted to have long-term benefits

CONCLUSIONS

Ultimately, the research could offer a comparative perspective on these therapies' efficacy, providing insights into tailored, accessible mental health support for students.

Community-Driven HPV Vaccination: A Living Systematic Review Protocol Using Ward Health Approaches (Preprint)
Authors: Raimi Morufu Olalekan , Adias Teddy Charles , Elemuwa Christopher Ononiwu
Published: November 2024

BACKGROUND

Human papillomavirus (HPV) vaccination is critical in the prevention of cervical cancer and other HPV-related diseases. Despite the availability of the HPV vaccine, significant barriers—such as vaccine hesitancy and limited community involvement—impede widespread vaccination uptake in Nigeria. These challenges underscore the need for strategies that effectively engage communities and address vaccine hesitancy.

OBJECTIVE

This living systematic review protocol aims to evaluate the effectiveness of utilizing the Ward Health System (WHS) approach to enhance community engagement and increase HPV vaccination acceptance in Nigeria.

METHODS

The review will adopt a comprehensive, iterative approach, starting with an initial systematic review and followed by bi-monthly updates over a 12-month period. Searches will be conducted across six major databases, including PubMed, Embase, Scopus, CINAHL, Web of Science, and African Journals Online, along with additional grey literature and preprint sources. Data will be synthesized through narrative synthesis, and meta-analysis will be performed where suitable. The quality of included studies will be assessed using the Mixed Methods Appraisal Tool (MMAT).

RESULTS

Findings from this living review will provide continuous, up-to-date evidence on the effectiveness of the WHS approach in enhancing HPV vaccination rates in Nigerian communities.

CONCLUSIONS

This protocol outlines a systematic approach to evaluating the WHS model’s impact on HPV vaccine uptake, potentially informing community engagement practices to address vaccine hesitancy and improve vaccination coverage. Upon completion, the findings from this review are expected to provide evidence-based recommendations for healthcare policymakers and practitioners on using WHS to enhance HPV vaccination acceptance in Nigeria. This review addresses a crucial gap in HPV vaccination uptake by assessing a community-based engagement model within Nigeria’s healthcare system. The findings may have broader implications for HPV vaccination strategies across similar low-resource settings.
Applications of Federated Large Language Model for Adverse Drug Reactions Prediction: A Scoping Review (Preprint)
Authors: Guo David , Choo Kim-Kwang Raymond
Published: November 2024

BACKGROUND

Adverse drug reactions (ADRs) pose significant challenges in healthcare, where early prevention is vital for effective treatment and patient safety.

OBJECTIVE

Traditional supervised learning methods are limited in addressing healthcare data, which is often unstructured, heavily regulated, and involves restricted access to sensitive personal information.

METHODS

The integration of Federated Learning (FL) and Large Language Model (LLM) offers a promising solution to these challenges since FL supports the distributed training on edge device with limited resources and the capability of LLM to deal with unstructured healthcare data. Additionally, client models trained on the edge device can be merged into a global model on the server, preserving data privacy.

RESULTS

Natural Language Processing (NLP) technologies underpinning LLM provide a full set of tools that can readily be used to process unstructured ADR as input, enabling LLM to predict ADR outcome effectively. The ADR output space can be discrete labels, unstructured texts, or both.

CONCLUSIONS

This review presents a scoping review following the PRISMA protocol on the applications of Federated Large Language Model (FedLLM) in ADR prediction, aiming to explore future research venue on ADR applications

BACKGROUND

Asthma exacerbations are a significant issue due to poor perception and failure of traditional monitoring techniques to capture real-time changes in respiratory function. There is a need for strategies to enhance recognition and facilitate timely intervention.

OBJECTIVE

To evaluate the efficacy of a respiratory-responsive vocal biomarker (RRVB), accessible via smartphone application, as a convenient real-time tool for monitoring asthma exacerbations and respiratory states.

METHODS

In this three-month prospective cohort study, 84 asthma patients recorded daily 6-second vocal samples, generating RRVB scores. The RRVB's ability to predict asthma exacerbations and respiratory states (normal function, mild events, exacerbations) was assessed using risk ratios (RR) and confidence intervals (CIs). Respiratory states were defined using peak expiratory flow (PEF) and self-reported wellbeing, with exacerbations identified by a decline in both PEF and wellbeing, and mild events by a decline in one measure.

RESULTS

RRVB scores significantly predicted asthma exacerbations, with a risk ratio of 2.15 (95% CI: 1.62-2.85, p < .001), and 3.57 (95% CI: 2.70-4.73, p < .001) using normalized scores adjusted for individual characteristics. However, time-averaged RRVB scores did not significantly correlate with asthma control as measured by the Asthma Control Test (ACT), with a risk ratio of 1.17 (95% CI: 0.96-1.44, p = .12). A total of 58% of participants remained engaged throughout the study, reporting high satisfaction with the tool's usability and perceived benefits for asthma management.

CONCLUSIONS

This study demonstrates potential enhancements in asthma management through more accessible and continuous monitoring of respiratory function offered by the RRVB tool, which was shown to provide an effective, real-time, and user-friendly approach for detecting potential exacerbations.
