Abstract
Acoustic Event Detection and Classification (AEDC) aims to identify and classify specific audio events within audio signals. AEDC has applications in various fields, including security systems, scene monitoring, smart hospitals, environmental monitoring, and more. The process of AEDC typically involves steps that include audio signal processing to extract relevant features from the input, a machine learning model to recognise patterns in the extracted features and a classifier to detect events. Recent research on AEDC has increasingly focused on features based on the frequency distribution of the Mel-frequency cepstral coefficients (MFCCs). In this study, the feature extraction is performed based on Cochleogram, which involves the analysis of audio signals using Gammatone filters. Cochleogram features are inspired by the human cochlea, part of the inner ear responsible for converting sound vibrations into electrical signals sent to the brain. A two-dimensional (2D) feature is extracted from the Cochleogram using Welch’s spectral density estimation and then converted into a frequency spectrum. The frequency distribution of different cochleogram filter banks is then used as a one-dimensional (1D) feature. The proposed classification method uses a 1D Convolutional Neural Network (CNN), which is less complex than traditional 2D CNNs. The proposed method was evaluated using the URBAN-SED dataset, and its performance was compared against the related state-of-the-art methods. The results showed the competitiveness of the cochleogram over Mel-based features such as MFCC in AEDC if the deep learning algorithm is properly designed and trained. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.

EUROPEAN BURN JOURNAL
Abstract
The rehabilitation of burn patients is essential and is intrinsically linked to conventional rehabilitation; the motivational challenges faced by burn patients in maintaining engagement with these rehabilitation programs are well known. It is understood that the use of other resources, particularly technological ones, associated with conventional rehabilitation could overcome these constraints and thereby optimize the rehabilitation program and health outcomes. The objective of this study is to synthesize the available evidence on the use of exergames in rehabilitation programs for burn patients. This systematic review was developed following the guidelines of the Joanna Briggs Institute (JBI). The search was conducted in the following databases: Medline (R), CINAHL (R), Sports Discus (R), Cochrane (R), and Scopus (R) during May 2025. The PRISMA Checklist Model was used to organize the information from the selected studies. Seven RCTs were included, involving a total of 236 participants. Outcomes related to the use of exergames in the rehabilitation of burn patients were identified, including increased range of motion, functionality, strength, speed of movement, improved balance, reduced fear and pain, and satisfaction with the technological resource used. It is believed that the results of this review, which confirmed the advantage of using exergames, such as Nintendo Wii, PlayStation, Xbox Kinect, or Wii Fit, to optimize the functionality of burn patients, can support clinical decision-making and encourage the integration of exergames to improve rehabilitation programs for burn patients.

Abstract
Introduction: The importance of investigating innovative technologies to improve patient rehabilitation is fundamental in the current context of healthcare. This highlights the need to map the technological resources used in the rehabilitation of adult burn patients. Methods: A scoping review was conducted according to the parameters set by the Joanna Briggs Institute (JBI) guidelines and structured using the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and MetaAnalyses for Scoping Reviews). The scientific literature search covered various databases: Medline, CINAHL, SportDiscus, Psychology & Behavioral Sciences Collection, Scopus, SciELO, and the Cochrane Library. The inclusion criteria considered studies related to the use of technological resources in the rehabilitation of burn patients. The research was conducted until November 2024. Results: A total of 19 articles published between 2000 and 2024 were included. The technological resources analyzed included virtual reality (10 studies), exergames (6 studies), exoskeletons (4 studies), and augmented reality (1 study). These resources primarily aimed to promote motor functionality, increase muscle strength, and enhance joint range of motion. Conclusion: The technologies applied to the rehabilitation of burn patients represent a promising advancement, with the potential to transform the paradigm of rehabilitation, making it more interactive. Future research should focus on a detailed analysis of the long-term benefits and on integrating these technologies into standard rehabilitation protocols.

Abstract
To address the challenges of self-care in oncology, gamification emerges as an innovative strategy to enhance health literacy and self-care among individuals with oncological disease. This study aims to explore and map how gamification can promote health literacy for self-care of oncological diseases. A scoping review was conducted following the Joanna Briggs Institute guidelines and the PRISMA-ScR Checklist developed for scoping reviews. A comprehensive search strategy was employed across MEDLINE (R), CINAHL (R), Scopus (R), and Web of Science (R) databases, with keywords focusing on oncological patients and gamification tools applied to self-management, from inception to December 2023. Thirty studies published between 2011 and 2023 were included, with a total of 1,118 reported participants. Most interventions (n = 21) focused on the development of mobile applications. The most frequent gamification elements included customizable avatars, rewards, social interaction, quizzes, and personalized feedback. The interventions primarily targeted health literacy and patient education, symptom monitoring, management of side effects, pain control, and adherence to medication and nutrition regimens. The integration of gamification elements into digital health solutions for oncology is expanding and holds promises for supporting health literacy and self-care. Further studies, preferably longitudinal, are needed to assess the effectiveness and impact of these interventions across different oncological populations and clinical settings.

Abstract
Objective: This scoping review synthesized and mapped the breadth of the existing literature on technological resources used to support individuals undergoing hemodialysis treatment. Methods: Following the methodological guidelines of the Joanna Briggs Institute (JBI) for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist, comprehensive searches were conducted across the following databases: MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Scopus, Scientific Electronic Library Online (SciELO), MedicLatina, and the Cochrane Central Register of Controlled Trials, with no time restrictions. Results: Thirty-nine studies conducted between 2003 and 2023 met the inclusion criteria. These studies covered a range of technological innovations developed specifically for hemodialysis treatment, including virtual reality, exergames, websites, and mobile applications. These technologies were designed with diverse objectives: to facilitate physical exercise, optimize dietary and medication management, improve disease adherence and management, and promote self-efficacy and self-care in patients. Conclusions: The review revealed a wide range of technological resources available to hemodialysis patients. These digital solutions show great potential to transform care by promoting more engaged and personalized health practices. Although this study did not directly assess the impact of these technologies, it provides a solid foundation for future investigations that can explore in-depth how such innovations contribute to effective disease management and improvement in clinical outcomes.

Abstract
BackgroundIndividuals with spinal cord injury (SCI) face complex and ongoing rehabilitation needs. In this context, mobile health applications have emerged as promising tools to support self-management and rehabilitation.ObjectiveTo map and characterize mobile applications specifically developed to support rehabilitation of individuals with SCI.MethodsA scoping review was conducted in accordance with PRISMA-ScR guidelines. A systematic search was performed across five electronic databases (PubMed, Scopus, Web of Science, and CINAHL). Studies published between 2015 and 2024 describing the use of mobile applications in the rehabilitation of adults with SCI were included.ResultsA total of 24 studies were included. We synthesized the identified applications descriptively into four domains: self-management and health education; gamification and motivation for physical rehabilitation; monitoring and prevention of secondary complications; and assistive technology and advanced rehabilitation. A consistent adoption of user-centered design principles was observed. Despite high levels of reported usability, challenges remain regarding long-term engagement, technological complexity, and sustained adherence.ConclusionMobile applications represent a promising complementary resource to support rehabilitation and health management in individuals with SCI. However, more robust longitudinal studies with larger sample sizes are required to assess the clinical impact and long-term feasibility of these interventions.
