Data sharing is increasingly important across various industries. However, issues such as data integrity verification during sharing, encryption key leakage, and difficulty sharing data between different user groups have been identified. To address these challenges, this study proposes a multi-group data sharing network model based on Consortium Blockchain and IPFS for P2P sharing. This model uses a dynamic key encryption algorithm to provide secure data sharing, avoiding the problems associated with existing data transmission techniques such as key cracking or data leakage due to low security and reliability. Additionally, the model establishes an IPFS network for users within the group, allowing for the generation of data probes to verify data integrity, and the use of the Fabric network to record log information and probe data related to data operations and encryption. Data owners retain full control over access to their data to ensure privacy and security. The experimental results show that the system proposed in this study has wide applicability.

Introduction: We compared and measured alignment between the Health Level Seven (HL7) Fast Healthcare Interoperability Resources (FHIR) standard used by electronic health records (EHRs), the Clinical Data Interchange Standards Consortium (CDISC) standards used by industry, and the Uniform Data Set (UDS) used by the Alzheimer's Disease Research Centers (ADRCs).
Methods: The ADRC UDS, consisting of 5959 data elements across eleven packets, was mapped to FHIR and CDISC standards by two independent mappers, with discrepancies adjudicated by experts.
Results: Forty-five percent of the 5959 UDS data elements mapped to the FHIR standard, indicating possible electronic obtainment from EHRs.

Background: Older adults in rural China bear a significant proportion of their healthcare expenses through out-of-pocket payments, resulting in a considerable financial burden on their families.
Objective: This study aimed to explore the key factors influencing adult children's involvement in financing healthcare expenses for their elderly parents in rural China.
Methods: Data were collected by in-depth interviews using a semi-structured interview guide approved by all researchers.

Adult congenital heart disease (ACHD) constitutes a heterogeneous and expanding patient cohort with distinctive diagnostic and management challenges. Conventional detection methods are ineffective at reflecting lesion heterogeneity and the variability in risk profiles. Artificial intelligence (AI), including machine learning (ML) and deep learning (DL) models, has revolutionized the potential for improving diagnosis, risk stratification, and personalized care across the ACHD spectrum.

Cultural transmission across generations is key to cumulative cultural evolution. While several mechanisms-such as vertical, horizontal, and oblique transmission-have been studied for decades, how these mechanisms change across the life course, beyond childhood, remains unclear. Furthermore, it is under-explored whether different mechanisms apply to distinct learning processes: long-term learning-where individuals invest time and effort to acquire skills-and short-term learning-where individuals share information of immediate use.

Prurigo nodularis (PN) is a chronic skin inflammatory condition characterized by severe, persistent itching and excoriated nodules induced by scratching. PN is strongly related to neural and immune dysfunction and negatively impacts quality of life. Treatments for PN are often off-label, highlighting the need for specifically approved agents and consensus guidelines for patient management.
