Background: Physical activity is widely recommended for preserving musculoskeletal health and managing osteoarthritis-related pain, although its benefits are commonly framed in terms of muscle strengthening, weight control, and physical performance. This narrative review aimed to examine movement more broadly as a physiological regulator of synovial joint homeostasis, sensory calibration, and functional adaptation. Methods: A structured literature search was performed in PubMed/MEDLINE, Scopus, and Web of Science from database inception to 1 February 2026. Experimental studies, observational studies, clinical trials, systematic reviews, meta-analyses, and selected narrative reviews addressing movement-responsive joint biology or pain regulation were considered. Evidence was synthesized across four interrelated domains: mechanical, fluidic, immune-metabolic, and sensory regulation. Results: The narrative synthesis indicates that the concept of the synovial joint as a dynamic mechano-fluidic organ in which cartilage, synovium, synovial fluid, capsule, subchondral bone, periarticular tissues, and sensory pathways interact continuously. Repeated physiological movement may promote synovial fluid exchange, lubrication, cartilage nutrition, hyaluronic acid and lubricin function, matrix turnover, anti-inflammatory signaling, proprioceptive control, and exercise-induced hypoalgesia. In contrast, inactivity and unloading may impair fluid dynamics, promote muscle inhibition, stiffness, inflammatory persistence, sensory deconditioning, and loss of function. Excessive or poorly distributed loading may also disrupt homeostasis through matrix injury, inflammation, fatigue, and nociceptive sensitization. These findings informed the proposed adaptive loading window, a hypothesis-generating conceptual framework rather than a clinically validated threshold, describing the dynamic range of movement within which joint function and pain regulation may be supported without sustained tissue or symptom aggravation. Conclusions: Movement should be viewed not only as a therapeutic intervention, but also as a continuous regulator of joint biology and perception. Its clinical value may depend on identifying an individualized loading range that supports adaptation, function, and confidence in movement while avoiding both underloading and overload.

IoT-connected healthcare sensor networks require authenticated and privacy-preserving data exchange among wearable sensors, mobile medical terminals, edge gateways, cloud servers, and medical institutions. Existing authentication schemes for healthcare IoT often bind signatures directly to user identities, exposing sensitive personal or institutional information and imposing heavy verification costs on resource-constrained sensing devices. To address this problem, we propose a fine-grained and flexible dual authentication scheme for healthcare sensor networks. In the proposed scheme, health data and diagnoses are signed with a fresh signing key and a fine-grained access control policy each time, so that the signer identity remains hidden while authorized entities can still modify permitted parts of signed data. No entity other than an authorized entity can trace a malicious signer or modify signed data without changing the data source. To support lightweight verification in sensor-edge-cloud deployments, we further present a verifiable outsourced authentication scheme that outsources time-consuming pairing operations to cloud servers; the online verification process then requires only six multiplication operations. As a fundamental technical component, we present a practical attribute-based sanitizable signature with shorter signature and key lengths and more efficient signing and signature-changing operations than the state-of-the-art policy-based sanitizable signature (P3S). Formal security analysis and experiments demonstrate the security and practicality of the proposed scheme for privacy-preserving healthcare sensing and medical data exchange. Full article

Background: Q&A corpora generated through university student–AI mental health support tools may reveal how physical activity (PA) and psychosocial themes are represented in support-oriented text. However, the absence of individual-level demographic metadata and the pooling of prompt and response fields limit attribution of any expression to a particular speaker, and the corpus describes a specific student population rather than a general or clinical one. Objective: This exploratory study described PA-, sport-, physical education (PE)-, body-, lifestyle-, and emotion-related patterns in a large corpus of university student–AI mental health exchanges collected through an institutional counselling platform. Methods: This study analysed 209,715 paired prompt–response records as combined exchange-level units using a BERTopic-based computational text-mining workflow. The full corpus was used for the main 18-topic model and overlapping dictionary analyses. After secondary data-quality filtering, 178,062 eligible exchanges formed the sampling frame from which a systematic sample of 10,000 exchanges was drawn for a separate complementary BERTopic and scenario-mapping analysis. The workflow used Qdrant/bge-small-zh-v1.5 embeddings, NFKC normalisation, an archived stop-word list, UMAP (n_neighbors = 15, n_components = 5, min_dist = 0.0, cosine metric, seed = 42), HDBSCAN (min_cluster_size = 300, min_samples = 10, Euclidean metric, EOM), c-TF-IDF topic representations, overlapping dictionary screens, and stability testing across seeds 42, 52, and 62. Results: A student/school/family-context lexical screen matched 83,215 exchanges (39.68%), and a broad PA/body/lifestyle screen matched 82,464 exchanges (39.32%). These overlapping indicators describe topical co-occurrence and do not establish PA behaviour or which party to the exchange produced a given term. Eighteen corpus-level themes were retained. In the 10,000-exchange analysis, 13.11% of exchanges matched a narrow movement-related expression screen, with the highest within-topic rate in the sample topic labelled emotional outburst and relaxation regulation (51.09%). Conclusions: The findings describe exchange-level lexical and topic patterns in student–AI interactions rather than actual PA behaviour, intervention delivery, clinical efficacy, or population prevalence, and they do not identify which party introduced the language. The mapping to autonomy, competence, relatedness, and emotional regulation is a post hoc interpretive lens, offered as a hypothesis to inform future, prospectively validated design work in PE and digital mental health support rather than as a demonstrated result.

Extensive industry efforts have led to the delivery of information supporting farmer production practices, including soil management. Education and extension activities are vital, with wide-ranging information sources being delivered to inform decisions around sustainable food production practices. Despite this, there remain knowledge gaps about actual and preferred delivery of soil indicator information for Australian farmers and supportive stakeholders, including advisors and researchers. This research explored the current and preferred sources for delivering information about soil indicators for farmers and industry stakeholders across different farming enterprises (cattle, grains, and sheep). Data were collected using a 20-item survey. Survey responses (N = 265) were received from farmers (n = 156), advisors (n = 72), and researchers (n = 37) to understand how they currently receive soil indicator information, what sources they prefer for receiving this information, and the relationships between sources of soil indicator information to support farming practices. The findings indicate that farmers receive soil information from many sources but prefer to receive it from industry advisors—including researchers; farmer, grower, and producer groups; agronomists; and consultants—and at industry events such as field days, farm walks, and tours, as well as via education and training. The findings demonstrate that information about soil health for farmers must be delivered by trusted individuals and organisations in ways that farmers will find, understand, access, and use. This includes prioritising information delivery through stakeholder engagement and connections, to foster personalised information exchange. In contrast, no preferred information sources were identified for advisors and researchers. While online sources of information delivery are increasing in the digital age, this study did not identify any strong associations between farmers and these approaches. This study highlights the pivotal role that trusted industry intermediaries have in delivering information about soil indicators. This identifies a priority for future support that is directed towards industry advisors and researchers to optimise their delivery of soil health information to farmers. Full article

Public responses during health crises are shaped by interacting risk perceptions, affect, trust, information needs, overload, misinformation, and protective behavior. Existing applications of the Risk Information Seeking and Processing (RISP) model are largely static and therefore cannot represent stochastic multichannel exposure, delayed correction, or policy feedback. We develop the Stochastic Probabilistic Dynamic RISP (SP-D-RISP) model, which recasts RISP as a bounded stochastic state-space system. Its symmetry structure is explicit: the channel-allocation mechanism is equivariant under simultaneous relabeling of channels and their parameter blocks, while the multi-agent dynamics are invariant to agent relabeling under exchangeable sampling and a label-independent policy. Channel-specific effects, heterogeneous traits, rumor shocks, and interventions generate symmetry breaking. The model combines softmax–multinomial channel competition, discounted Bayesian trust updating, and policy-coupled state transitions. Projection guarantees feasible states by construction, whereas stronger stochastic stability is conditional on a coefficient-level small-gain criterion. For the stationary bounded-memory specification, this criterion is sufficient for Wasserstein contraction, uniqueness of the invariant distribution, and geometric forgetting of initial conditions. The criterion is formulated at the coefficient level and is kept distinct from finite-horizon simulation diagnostics. For the fully disclosed semi-synthetic coefficient vector, the scenario-specific gain matrices have spectral radii between $0.852765$ and $0.857123$; the worst-case column-sum norm is $0.983948$. Thus, the fixed-policy kernels satisfy the stated contraction certificate. For deterministic time-varying paths, the calculation is used only as a common-path one-step certificate, and for the threshold-adaptive rule, it is used only mode by mode rather than as a stationary invariant-law claim. While concentration bounds and Monte Carlo inference quantify population and replication uncertainty, a semi-synthetic experiment with 2500 heterogeneous agents over 90 days examines trust and literacy heterogeneity, clarification delays, communication volume, and intervention portfolios. Within the calibrated SP-D-RISP scenarios, the simulations suggest that higher communication volume may reduce modeled protective behavior when overload effects dominate knowledge gains, delayed clarification may increase transient misinformation, and an integrated portfolio can yield a more favorable simulated outcome profile than the evaluated single-lever strategies.

Wood-based materials are a significant source of formaldehyde (HCHO), which is a volatile organic compound (VOC) classified as a human carcinogen that has adverse effects on the indoor air quality (IAQ) and health. This study evaluates HCHO emissions from six materials commonly used indoors, including medium-density fiberboard, melamine, pine boards, birch boards, oak boards, and alder boards, using the desiccator method in accordance with ASTM D5582. The experimental results were integrated with an indoor air model to estimate exposure under representative residential conditions. The measured emissions ranged from 0.235 ± 0.01 to 1.023 ± 0.10 mg m⁻³, with composite materials exhibiting the highest values. The risk analysis showed that all samples exceeded international reference values, with the greatest concern arising in scenarios of chronic exposure. The modeling indicated that indoor air concentrations depend heavily on material load and ventilation, reaching values as high as 0.155 mg m⁻³ under conditions of low air exchange. Overall, the results show that material composition, installed quantity, and ventilation conditions are key factors influencing indoor HCHO concentrations. This study offers an integrated approach that combines experimental measurement and exposure estimation, contributing to informed material selection and the assessment of their impact on IAQ.

The research aimed to understand the different cultural needs relating to death and dying of migrant populations in Western Sydney, Australia, and how end-of-life care can be provided in culturally safe ways which can, in turn, inform the policies that shape palliative care and bereavement service delivery. The mixed methods design for this study used an online quantitative survey using the Death Literacy Index, key informant qualitative interviews, culture-based community focus groups, and individual Photovoice interviews with carers. In all, 266 participants across the three largest migrant communities and local area health services took part in the research. The results revealed the importance of cultural practices and rituals for people at end of life and that providing space for these is crucial to cultural safety in service contexts, in addition to relational trust and the need for community input to improve the services that affect them. There is also a need for greater knowledge and understanding in the end-of-life space through two-way exchanges between communities and service providers. Finally, there are important ways that the existing services can facilitate cultural safety and ways of increasing the availability of culturally appropriate end-of-life and bereavement services for the community.

The fragmentation of clinical information across health systems, community pharmacies, and specialty providers continues to undermine medication safety and emergency care, particularly when patients are unconscious or otherwise unable to communicate their history. The dominant response to this fragmentation has been the construction of a centralized data infrastructure—health information exchanges, prescription drug monitoring programs (PDMPs), and federated electronic health record (EHR) networks—that aggregates clinical information into institutional databases that are queryable by providers, insurers, regulators, and, in many jurisdictions, law enforcement. This article argues that the same care-coordination problems can be addressed through an architecturally different approach in which the patient, not the institution, holds the integrative artifact. The proposed design, here labeled the Guardian Card (a conceptual architecture, not a commercial product), pairs an HL7 Fast Healthcare Interoperability Resources (FHIR) clinical payload with the SMART Health Cards verifiable-credential framework and a dual-modality (QR code plus near-field communication) physical carrier. After describing the technical architecture, hardware options, and a five-phase deployment roadmap, the design is situated within the surveillance-critical scholarship that has documented PDMP function creep, third-party doctrine erosion, racial disparities in algorithmic prescribing oversight, and the surveillance-instrumentarian repackaging of nominally de-identified prescription data. The Guardian Card is offered as one operational implementation of a patient-controlled medication-record architecture, with community pharmacy and long-term post-acute care, where the Pharmacist eCare Plan integration is most feasible as a recommended first-deployment venue.

The safety of non-food products is embedded in the United Nations 2030 Agenda for Sustainable Development and the European Union (EU) framework, supporting health protection, responsible production and consumption, and market surveillance. The EU Rapid Alert System for dangerous non-food products, known as Safety Gate (formerly RAPEX), was established in 2005 to facilitate the exchange of information on products posing risks within the internal market. The aim of this study was to present the interdependencies reported in the Safety Gate system/RAPEX in 2005–2025, considering: product category, type of risk, country of origin, notifying country and year, as well as measures taken. The VOSviewer 1.6.20 and Statistica 13.3 were used. The results highlighted the following problems: toys from China with chemical, choking and injury risks; electrical appliances also from China with electric shock hazards; motor vehicles from Germany with injury risks; cosmetics from Italy with chemical and microbiological risks; and clothing from Turkey with suffocation risks. Reporting is expected to continue under existing regulatory frameworks, although changing the name of the system from RAPEX to “Safety Gate” may reduce its recognition. The findings highlight the need for targeted enforcement, improved risk profiling by product category and origin, and ongoing monitoring of emerging safety risks. Full article

Maternal psychoactive substance use during pregnancy represents a major threat to placental integrity and fetal development. As the central interface for maternal–fetal exchange, the placenta is highly susceptible to psychoactive substances, including alcohol, tobacco, cannabis, cocaine, opioids, and synthetic drugs, which can cross the placental barrier and induce structural and functional alterations. This review synthesizes current evidence on the biological mechanisms, diagnostic approaches, and forensic relevance of psychoactive substances-induced placental pathology. We summarize how different substances disrupt placental vascularization, oxidative balance, epigenetic regulation, and cellular viability, leading to impaired nutrient and oxygen transfer and increasing the risk of adverse outcomes such as intrauterine growth restriction, preterm birth, congenital anomalies, and long-term neurodevelopmental impairment. We further discuss the role of placental tissue in identifying prenatal drug exposure and reconstructing exposure timelines. Beyond its clinical relevance, placental examination provides objective evidence with potential forensic value in cases of suspected maternal substance use, while also informing non-punitive, evidence-based interventions. Overall, integrating placental pathology into reproductive health research and prenatal care offers a multidisciplinary framework to improve maternal–fetal outcomes and guide public health strategies addressing substance use during pregnancy.

Persons with Disabilities (PWDs) face persistent barriers to healthcare access, welfare services, and timely medical assistance, particularly where hospital information is fragmented across institutions. In Thailand, these challenges are exacerbated by heterogeneous Hospital Information Systems (HISs) across provincial, district, and sub-district hospitals. This study presents the design, implementation, and evaluation of an integrated mobile application and a hybrid Hospital Information Exchange (HIE) system to enhance healthcare accessibility and service coordination for PWDs. The platform integrates a user-centered mobile application (iOS and Android) with a hybrid data exchange architecture (MedEx Hybrid) combining an application programming interface (API) and Message Queuing Telemetry Transport (MQTT). This enables real-time and on-demand data exchange while accommodating hospitals with limited infrastructure. Key functionalities include disability registration, emergency medical service (1669) integration, appointment management, rights notification, service location mapping, teleconsultation, and peer communication. Deployment across 159 hospitals nationwide demonstrates system scalability and interoperability. The system supports secure access to electronic medical records and enables emergency responders to retrieve patient information during SOS events, improving continuity of care. Findings confirm the feasibility of the proposed system and its potential to support inclusive digital health and national healthcare interoperability. Full article

Practice-oriented or practice-based research is growing in popularity in the social, built environment and health fields for its important role in driving transformative changes at policy, programme/service and practice levels. As planning is a practice with performative characteristics occurring in a socio-political-legal context, practice-oriented research has been utilised to inform and help shape change. However, to be truly effective, practice-oriented research must be connected to day-to-day practices. In this article, we present our experience of using a Community of Practice (CoP)—that brings together people with shared interests and professions—to exchange learning and experiences and to help create knowledge to advance professional practice. In our case, we established a Community of Practice of Planners (CoPP) to help translate stage one findings into tailored knowledge resources to open up a dialogue and raise awareness on Planning for Disability Equity and Inclusion. In this article, we describe the method of CoP, how it works, including our reflections and learnings. We suggest that CoP are an underutilised method in planning practice and research. We argue that the CoP approach should be in a researcher and planner’s toolbox for more transformative progress in equity and inclusion in planning. Full article

For almost fifty years, Crew Resource Management (CRM) has been a cornerstone of aviation safety and training. This narrative review examines the current state of CRM training and identifies key directions for future development, including the integration of artificial intelligence, increasing attention on mental health and resilience, and workforce diversity. While there is evidence of gradual evolution in CRM practices, reflected in updated regulatory frameworks, competency-based approaches, and a growing community of human factors and aviation psychology specialists, progress remains uneven across the industry. We argue that many aviation operators and training organizations still lack robust institutional mechanisms to systematically translate emerging scientific evidence into training design and delivery. As a result, advances in research on teaching and learning methods and human performance are not consistently brought forward into everyday training practices. The review concludes with a set of practical recommendations aimed at strengthening knowledge exchange between researchers and operational stakeholders, enhancing evidence-informed training, and supporting the modernization of CRM in a rapidly changing operational environment.

Southeast Asia (SEA) faces persistent gaps in regional understanding and control of ticks and tick-borne diseases (TBDs) despite recent advances (2023–2025). The second international symposium on ticks and TBDs in SEA (Singapore, August 2025), following the inaugural 2023 meeting in Cambodia, served as a catalyst for regional exchange that informed this perspective. SEA’s ecological and host diversity supports complex tick–host–pathogen networks, yet evidence remains fragmented due to uneven sampling that has largely focused on livestock and peri-urban environments. Key constraints include limited taxonomic resolution driven by outdated or incomplete identification keys, under-sampling of soft ticks (Argasidae), and the absence of harmonized, open-access regional reference resources (including DNA barcodes and MALDI-TOF MS spectral databases). While MALDI-TOF MS, proteomics, AI-assisted identification, and next-generation sequencing/metagenomics are increasingly applied, their broader regional uptake is limited by the absence of harmonized, open-access reference resources (including DNA barcodes and MALDI-TOF MS spectral databases). Broad ecological surveys and integrated animal and human surveillance remain limited, and vector competence studies are constrained by the scarcity of SEA-derived tick colonies and cell lines. Regional data and recent findings (2024–2026) confirm circulation of multiple TBPs (including Anaplasma, Babesia, Borrelia, Coxiella, Ehrlichia, Rickettsia, and Theileria) and highlight emerging viral findings, including southward reports of Bandavirus dabieense. Human infestations and non-communicable tick bite outcomes (e.g., tick paralysis and alpha-gal syndrome) are recognized but remain under-reported due to low clinical awareness and limited diagnostics. Importantly, the diagnostic chain is further disrupted by missed/insufficient specimen collection at the point of care, and by constrained capacity to identify (especially immature) ticks to species level—limitations compounded by the absence of harmonized, open-access regional reference resources. The symposium identified six priorities: (1) full completion and regional validation of tick identification keys for adults (in progress) and immatures (to be initiated), plus an open-access DNA barcode library anchored by curated, voucher-based collections from all SEA countries; (2) harmonization of molecular and proteomic diagnostic platforms, including expansion of regional MALDI-TOF MS and NGS protocols and reference databases; (3) development of tick colonies and cell lines from locally prevalent species to support vector competence, vaccine, and acaricide testing; (4) expansion of One Health surveillance with enhanced ecological sampling at wildlife–livestock–human interfaces; (5) establishment of open-access, region-wide data platforms for integrated tick, TBP, and ecological metadata sharing; and (6) sustained investment in human resources, training, and policy advocacy to raise research and public health visibility of ticks and TBDs.

Objectives: Improving the interoperability of electronic health records is critical for efficient, cost-effective delivery of quality services, enhanced care coordination, and improved treatment outcomes within the United States healthcare system. Healthcare leaders and administrators often experience EHR interoperability issues, restricting communication between health systems and impacting electronic health data utilization. Methods: This systematic literature review explored innovative strategies to improve electronic health record interoperability between health information systems to enhance data exchange efficiency, accuracy, and security in U.S. healthcare settings. A search transpired using the Public Medline, Institute of Electrical and Electronics Engineers Xplore Digital Library, and Cumulative Index to Nursing and Allied Health Literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Data from 24 relevant articles were analyzed using screening criteria revolving around the research question. Five themes emerged during data analysis. The themes included the utilization of blockchain-based EHR systems (67%), the drive of the Cures Act to achieve interoperability (17%), the advent of artificial intelligence and how it can be used (33%), how the Internet of Things drives the industry to strategically enhance the system (33%), and how the value of interoperability drives outcomes (79%). Conclusions: Findings indicate strategies from a technical perspective and from policy initiatives can improve communication between health information systems. Findings suggest that by strategically leveraging available resources and implementing innovative strategies, healthcare leaders can achieve comprehensive EHR interoperability long term. Full article
