The dissemination of novel biomedical knowledge in scientific literature necessitates immediate and thorough engagement in modern times. Information extraction pipelines can automatically glean meaningful connections from textual data, demanding subsequent confirmation from knowledgeable domain experts. During the two decades past, much work has been done in analyzing associations between phenotype and health factors; however, the impact of food, a significant environmental consideration, has remained unexamined. In this study, we introduce FooDis, a novel pipeline for Information Extraction. This pipeline uses state-of-the-art Natural Language Processing methods to mine biomedical scientific paper abstracts, automatically suggesting probable cause-and-effect or treatment relationships involving food and disease entities from different existing semantic repositories. A scrutiny of existing relationships against our pipeline's predictions shows a 90% concordance for food-disease pairs shared between our results and the NutriChem database, and a 93% alignment for those pairs also found on the DietRx platform. The comparison showcases the high precision of the FooDis pipeline in relation suggestion. The FooDis pipeline can be further utilized for the dynamic identification of fresh connections between food and diseases, necessitating domain-expert validation and subsequent incorporation into NutriChem and DietRx's existing platforms.

Real-life data recording is a key benefit of mHealth apps, making them valuable adjuncts to treatment regimens, such as in supporting therapies. In spite of this, datasets of this nature, especially those derived from apps depending on voluntary use, frequently experience inconsistent engagement and considerable user desertion. The data's utilization via machine learning is hampered, and this casts a shadow on whether users continue to employ the application. This extended paper describes a method for identifying phases with varying dropout rates in a dataset, and for predicting the dropout rate for each phase in the dataset. Another contribution involves a technique for determining the expected period of a user's inactivity, leveraging their present condition. Phase identification leverages change point detection, showcasing the methodology for handling uneven, misaligned time series and predicting user phase through time series classification. We further delve into the development of adherence, tracing its evolution within subgroups. Using data collected from a tinnitus-specific mHealth app, we evaluated our method, finding it appropriate for evaluating adherence patterns within datasets having irregular, misaligned time series of varying lengths, and comprising missing data.
Precisely addressing missing values is fundamental to delivering dependable estimations and choices, especially within the demanding realm of clinical research. Deep learning (DL) imputation methods have been developed by many researchers in response to the multifaceted and varied nature of data. A systematic review was undertaken to assess the application of these techniques, emphasizing the characteristics of data gathered, aiming to support healthcare researchers across disciplines in addressing missing data issues.
Articles published before February 8, 2023, pertaining to the utilization of DL-based models for imputation were retrieved from five databases: MEDLINE, Web of Science, Embase, CINAHL, and Scopus. From four distinct vantage points—data types, model architectures, imputation methods, and comparisons to non-deep-learning approaches—we analyzed a selection of articles. Data types informed the construction of an evidence map visualizing deep learning model adoption.
Within a corpus of 1822 articles, 111 were deemed suitable for inclusion, with tabular static data (29%, 32/111) and temporal data (40%, 44/111) representing the most prevalent categories. The research concluded with the revelation of a distinct trend in the selection of model backbones and data types, exemplified by the widespread adoption of autoencoders and recurrent neural networks for handling tabular temporal data. A difference in the methods used for imputation was also observed, depending on the data type. A popular method for imputation, encompassing simultaneous resolution of imputation and downstream tasks, was predominantly utilized for tabular temporal datasets (52%, 23/44) and multi-modal datasets (56%, 5/9). Deep learning imputation methods consistently outperformed non-deep learning methods in terms of imputation accuracy across numerous investigations.
Deep learning-based imputation methods exhibit a spectrum of network structures. Healthcare designations are frequently customized according to the distinguishing features of data types. Deep learning-based imputation, while not universally better than traditional methods, may still achieve satisfactory results for particular datasets or data types. Despite advancements, current deep learning-based imputation models still face challenges regarding portability, interpretability, and fairness.

Natural language processing (NLP) tasks within medical information extraction collectively transform clinical text into a structured format, which is pre-defined. Electronic medical records (EMRs) depend on this critical action for their full potential. Considering the current flourishing of NLP technologies, model deployment and effectiveness appear to be less of a hurdle, while the bottleneck now lies in the availability of a high-quality annotated corpus and the entire engineering process. This study's engineering framework revolves around three distinct tasks: medical entity recognition, relation extraction, and attribute extraction. The demonstrated workflow within this framework encompasses the entire process, from EMR data acquisition to model performance evaluation procedures. For seamless compatibility across multiple tasks, our annotation scheme has been comprehensively crafted. Our corpus's large scale and high quality are ensured by electronic medical records from a general hospital in Ningbo, China, and the manual annotation process conducted by experienced physicians. The medical information extraction system, founded on this Chinese clinical corpus, performs with accuracy that approximates human annotation. The annotation scheme, along with (a subset of) the annotated corpus, and the corresponding code, are all publicly released to support further research.
