Interference between pharmacological substances can cause serious medical injuries. Correctly predicting so-called drug-drug interactions (DDI) does not only reduce these cases but also result in a reduction of drug development cost. Presently, most drug-related knowledge is the clinical evaluations and post-marketing surveillance; resulting limited amount information. Existing data-driven prediction approaches for DDIs typically rely on single source information, while using information...
In recent years, as newer technologies have evolved around the healthcare ecosystem, more and data been generated. Advanced analytics could power collected from numerous sources, both institutions, or generated by individuals themselves via apps devices, lead to innovations in treatment diagnosis of diseases; improve care given patient; empower citizens participate decision-making process regarding their own health well-being. However, sensitive nature prohibits organizations sharing data....
Abstract Although rare diseases (RDs) affect over 260 million individuals worldwide, low data quality and scarcity challenge effective care research. This work aims to harmonise the Common Data Set by European Rare Disease Registry Infrastructure, Health Level 7 Fast Healthcare Interoperability Base Resources, Global Alliance for Genomics Phenopacket Schema into a novel disease common model (RD-CDM), laying foundation developing international RD-CDMs aligned with these standards. We...
In recent years, data-driven medicine has gained increasing importance in terms of diagnosis, treatment, and research due to the exponential growth health care data. However, data protection regulations prohibit centralisation for analysis purposes because potential privacy risks like accidental disclosure third parties. Therefore, alternative usage policies, which comply with present guidelines, are particular interest.We aim enable analyses on sensitive patient by simultaneously complying...
The explosion of data-driven applications using Artificial Intelligence (AI) in recent years has given rise to a variety ethical issues regarding data collection, annotation, and processing mostly opaque algorithms, as well the interpretation employment results AI pipeline. ubiquity negatively impacts sensitive areas, ranging from discrimination against vulnerable populations privacy invasion environmental cost that these algorithms entail, puts into focus on ever present domain ethics. In...
Medical real-world data stored in clinical systems represents a valuable knowledge source for medical research, but its usage is still challenged by various technical and cultural aspects. Analyzing these challenges suggesting measures future improvement are crucial to improve the situation. This comment paper such an analysis from perspective of research.
Abstract Digitization of medicine requires systematic handling the increasing amount health data to improve medical diagnosis. In this context, integration versatile diagnostic information, e.g., from anamnesis, imaging, histopathology, and clinical chemistry, its comprehensive analysis by artificial intelligence (AI)–based tools is expected precision therapeutic conduct. However, complex environment poses a major obstacle translation integrated diagnostics into research routine. There high...
Amid the coronavirus disease(COVID-19) pandemic, humanity experiences a rapid increase in infection numbers across world. Challenge hospitals are faced with, fight against virus, is effective screening of incoming patients. One methodology assessment chest radiography(CXR) images, which usually requires expert radiologist's knowledge. In this paper, we propose an explainable deep neural networks(DNN)-based method for automatic detection COVID-19 symptoms from CXR call DeepCOVIDExplainer. We...
Osteoarthritis (OA) is a degenerative joint disease, which significantly affects middle-aged and elderly people. Although primarily identified via hyaline cartilage change based on medical images, technical bottlenecks like noise, artifacts, modality impose an enormous challenge high-precision, objective, efficient early quantification of OA. Owing to recent advancements, approaches neural networks (DNNs) have shown outstanding success in this application domain. However, due nested...
Gradient inversion attacks can reconstruct the victim's private data once they have access to model and gradient. However, existing research is still immature, many are conducted in ideal conditions.
