Exploring environmental sustainability of artificial intelligence in radiology ::a scoping review
Objective : Artificial intelligence (AI) is increasingly used in radiology, but its environmental implications have not been sufficiently studied, so far. This study aims to synthesize existing literature on the environmental sustainability of AI in radiology and highlights strategies proposed to mitigate its impact. Methods : A scoping review was conducted following the Joanna Briggs Institute methodology. Searches across MEDLINE, Embase, CINAHL, and Web of Science focused on English and French publications from 2014 to 2024, targeting AI, environmental sustainability, and medical imaging. Eligible studies addressed environmental sustainability of AI in medical imaging. Conference abstracts, non-radiological or non-human studies, and unavailable full texts were excluded. Two independent reviewers assessed titles, abstracts, and full texts, while four reviewers conducted data extraction and analysis. Results : The search identified 3,723 results, of which 13 met inclusion criteria: nine research articles and four reviews. Four themes emerged: energy consumption (n = 10), carbon footprint (n = 6), computational resources (n = 9), and water consumption (n = 2). Reported metrics included CO2-equivalent emissions, training time, power use effectiveness, equivalent distance travelled by car, energy demands, and water consumption. Strategies to enhance sustainability included lightweight model architectures, quantization and pruning, efficient optimizers, and early stopping. Broader recommendations encompassed integrating carbon and energy metrics into AI evaluation, transitioning to cloud computing, and developing an eco-label for radiology AI systems. Conclusions : Research on sustainable AI in radiology remains scarce but is rapidly growing. This review highlights key metrics and strategies to guide future research and practice toward more transparent, consistent, and environmentally responsible AI development in radiology
Energy storage configuration in fuel cell electric vehicle ::an analysis on a real urban mission profile
Fuel cell electric vehicles (FCEVs) rely on a battery system to manage transient load demands and to recover braking energy. In recent years, hybrid topologies that also integrate supercapacitors have gained considerable attention, since they can improve system efficiency, driving dynamics, and component lifetime. Supercapacitors, thanks to their much higher power density compared to conventional batteries, are particularly promising for adoption in FCEVs. Most studies in the literature, however, evaluate these architectures under standardized homologation driving cycles. While such cycles provide a common benchmark for comparison, they generally exhibit less energy-intensive profiles and therefore do not fully capture the real operating demands of a vehicle. For this reason, the present work investigates the use of batteries and supercapacitors in FCEVs under an actual urban driving mission, where the route includes an experimentally measured altitude profile. This approach allows for a more realistic assessment of energy requirements. Furthermore, the analysis carried out in this study considers different powertrain configurations: the exclusive use of a battery, the sole use of a supercapacitor, and a hybrid combination of both systems. These scenarios are evaluated both for an FCEV that can only be refueled with hydrogen and for a plug-in hybrid version of the vehicle that can also recharge its battery from an external charging station
Co-designing pain education for schools in Switzerland
Background and aims: Approximately 26% of adolescents experience chronic pain. Pain science education may help adolescents better understand their own and others' pain. Co-design of pain education is needed to improve implementation and target public needs. This study aimed to co-design pain science education material for Swiss 9th-grade with teachers, students, and experts. Methods: The four phases of the Double Diamond Framework structured the co-design process. Two groups were formed: (1) three pain education experts and one anthropologist; and (2) three teachers and four students from Central Switzerland. Guided by two facilitators, the groups participated in eight iterative online workshops using design thinking methods, such as persona creation and role-play. Co-designers provided feedback using the Public and Patient Engagement Evaluation (PPEE) tool. Results: Co-designers developed a toolbox comprising five ‘modules’: (i) Pain is a common sensation, and each experience is unique; (ii) Pain has many causes and is influenced by various factors; (iii) The experience of pain can help protect us; (iv) Our brain and body are bioplastic; (v) I can influence my pain and others' pain. Learning outcomes, teaching content, and assessment methods were developed for each module. Conclusions: Students, teachers, and researchers successfully co-designed a pain science curriculum for Swiss schools. Future exploratory studies will test the curriculum's effects
La pratique avancée en physiothérapie (PAP) en Suisse romande ::état des lieux par une approche mixte
Situation initiale : La Pratique Avancée en Physiothérapie (PAP) se développe progressivement en Suisse pour répondre aux enjeux croissants du système de santé (augmentation des coûts, pénurie de professionnels et complexité des soins). Si un recensement a été réalisé en Suisse alémanique, peu d’informations sont disponibles pour la Suisse romande. Pourtant, plusieurs fonctions de pratique avancée ont déjà vu le jour, sous différentes formes, dans des hôpitaux, cliniques ou cabinets privés. Ce travail a pour objectif d’identifier les pratiques avancées existantes en Suisse romande dans divers milieux de soins, mais aussi de comprendre comment ces rôles ont été instaurés et quelles sont leurs fonctions et leurs exigences spécifiques. Il répondra aux questions suivantes : « Quelles sont les pratiques avancées en physiothérapie existantes dans les contextes hospitaliers, cliniques ou ambulatoires de Suisse romande ? Comment les rôles de pratique avancée se sont mis en place et quelles sont les fonctions et les exigences spécifiques associées ? » Méthodologie : Une étude mixte, en deux étapes, a été conduite. D’abord, une enquête quantitative par questionnaire a permis d’identifier les rôles de pratique avancée. Ensuite, des entretiens semi-dirigés ont approfondi la mise en place des rôles, leurs fonctions et les exigences associées. Les données ont été analysées de manière descriptive. Résultats : L’enquête a identifié 16 rôles de pratique avancée répartis dans cinq cantons, dont quatre en cours de développement. Parmi les cinq professionnels interrogés en entretien, quatre exercent comme « cliniciens spécialisés » et un occupe une fonction de « physiothérapeute praticien spécialisé ». Tous décrivent des rôles en constante évolution. Les conditions d’accès varient selon les institutions : master ou plusieurs CAS spécialisés, et deux à cinq années d’expérience. Les obstacles évoqués concernent notamment des facteurs humains, un manque de temps et de ressources. Les facilitateurs comprennent le soutien institutionnel et l’influence de la pratique infirmière avancée. Des compréhensions diverses de la PAP ont également émergé. Conclusion : Cette étude off re une vue d’ensemble des PAP en Suisse romande, clarifie leur implantation, leur fonctionnement et les compétences attendues. Elle souligne l’importance de les défi nir précisément pour favoriser une réglementation cohérente.Background During hospitalisation, older adults are at risk of experiencing functional decline unrelated to their initial condition, known as hospital-associated disability (HAD). HAD affects 37 % of hospitalised older adults. The population of older adults is expected to grow in the coming years, likely leading to an increase in cases of HAD. Published systematic reviews have certain limitations, leaving several questions unanswered about the prevention of HAD. Randomised controlled studies (RCT) with multiple training components (such as different strengthening and balance or walking components) are difficult to compare against single-component programmes. The aim of the study was to systematically evaluate the effectiveness of (single or multi-component) physical exercise programmes on the prevention of HAD in people over 65 years of age hospitalised in an acute care setting measured at hospital discharge. Methods Living systematic review with network meta-analysis of RCTs. As this study represents a living systematic review, findings are continuously updated. Physical exercise programmes were analysed as multi-component interventions. Risk of bias was evaluated using the ROBUST-RCT tool. Results In total 5967 records were screened for eligibility; 546 full texts were assessed, and 75 studies were included in the evidence synthesis. We analysed 19 pair-wise comparisons at discharge. Inconsistency in the network-analysis was low with I 2 = 8.6 %. The most effective programme was strengthening compared against usual care (SMD: 0.65; 95 % CI: 0.06; 1.24). The exercise programme with the highest precision was balance + strengthening + walking (SMD: 0.50; 95 % CI: 0.33; 0.67). Training focused on a single-component of basic daily activities was not more eff ective than usual care (SMD: –0.13; 95 % CI –0.44; 0.18). Conclusion This work enhances the understanding of how to prevent HAD by providing detailed insights into specifi c components of physical exercise. Currently, the intervention with the highest precision suggests using a multicomponent approach involving balance, strengthening, and walking components to prevent HAD in an acute care setting. A major issue with traditional systematic reviews is the lengthy publication process, which often results in findings becoming outdated by the time they are published. This living systematic review enables clinicians to stay current by rapidly integrating new findings into the evidence synthesis of HAD prevention

The impact of physical activity on the prevention of spine musculoskeletal disorders in lactating women in Cameroon
Abstract
Introduction: Spine musculoskeletal disorders (SMSDs) may interfere with breastfeeding and negatively impact maternal and
infant health. Physical activity (PA) is known to reduce the risk of musculoskeletal issues.
Objective: This study aimed to assess the impact of PA levels on the occurrence of SMSDs in Lactating Women in Cameroon.
Methods: This cross-sectional study conducted from September to December 2024 included 399 nursing women in the
Foumbot Health District, Cameroon using a consecutive non-probability convenience sampling. PA was assessed using the
International Physical Activity Questionnaire–Short Form (IPAQ-SF), and SMSDs were evaluated using an adapted version
of the Nordic Musculoskeletal Questionnaire (NMQ). Data were analyzed using SPSS version 23.0, and multivariate logistic
regression was used to identify associations. The level of significance was set at p < 0.05.
Results: The mean (SD) age of participants was 24.3 (5.1) years, and that of their infants was 11.1 (8.5) weeks. The Madonna
position was the most common breastfeeding position, used by 388 (97.2%) nursing women. Among participants, 236 (59.1%)
reported SMSDs, with the most affected region being the upper back 98 (41.5%). PA levels were high in 149 (37.3%) participants,
moderate in 208 (52.1%), and low in 42 (10.5%). No significant association was found between PA and SMSDs.
However, working in the informal sector significantly increased the risk of SMSDs (aOR =2.21, CI: 1.33–3.67, p=0.002).
Conclusion: SMSDs are highly prevalent in nursing women. Interventions should address occupational risk factors to reduce
their impact in similar settings
Numerical assessment of a modular steel sleeve connection with wedge locking mechanism for demountable structures
This paper presents the numerical assessment of a modular steel sleeve connection incorporating a wedge locking mechanism, developed to enhance reusability and sustainability in steel construction. The connection eliminates welding and drilling of the main members, enabling full disassembly and reuse. An adapted configuration was investigated for central column applications, where multiple beams frame into a single square hollow section column through a four-sided sleeve. Finite element models were developed in Abaqus to evaluate the structural response, focusing on stress redistribution, plastic strain development, and moment–rotation behavior. The results indicate that yielding shifts away from the column face toward the sleeve–beam interface, promoting hinge formation in the beam rather than in the joint core. The connection demonstrates semi-rigid behavior consistent with Eurocode classifications, with stiffness comparable to conventional bolted joints. Overall, the study highlights the potential of modular sleeve connections with wedge locking mechanisms as reliable, demountable alternatives to traditional welded or bolted joints, supporting circular economy strategies in steel construction
