Special Issue Information

Dear Colleagues,

With the digital health era revolutionizing patient care, health systems are focusing on identifying areas of improvement for both clinical practice changes as well as improved patient outcomes using biomedical data. In recent years, there has been an exponential growth in healthcare data, ranging from Electronic Health Records (EHR), medical imaging data, and data from in-home and in-hospital health tracking and diagnostic sensors. Healthcare data analytics have been shown to improve patient outcomes, such as reducing mortality and providing opportunities for personalized and early interventions, and to have operational benefits, such as identifying waste and optimizing healthcare spending. However, there are several unmet clinical needs and the utilization of biomedical data is still sub-optimal. Therefore, we have an opportunity to build efficient biomedical data-driven digital tools to improve patient care. Advanced biomedical data processing and analytics techniques leveraging the potential of artificial intelligence (AI), cloud computing, data mining, and data visualization, in addition to a multidisciplinary collaborative research environment with clinicians, are essential to enhance the ability of healthcare providers to optimize care delivery and improve patient outcomes. In the future, novel data analysis methods will be crucial to help transform healthcare systems from a reactive, treatment-based approach to a more integrated, preventive model. Novel machine learning-based clinical decision tools will become inevitable for an enriched healthcare system to provide much-needed care to patients in a timely fashion.

This Special Issue will provide an opportunity to showcase novel methodological innovation and translational efforts related to the analysis of various healthcare data, including EHR data, biomedical signals, and imaging data, to enhance patient care.

Accurate diagnosis of gastrointestinal (GI) diseases typically requires invasive procedures or imaging studies that pose the risk of various post-procedural complications or involve radiation exposure. Bowel sounds (BSs), though typically described during a GI-focused physical exam, are highly inaccurate and variable, with low clinical value in diagnosis. Interpretation of the acoustic characteristics of BSs, i.e., using a phonoenterogram (PEG), may aid in diagnosing various GI conditions non-invasively. Use of artificial intelligence (AI) and improvements in computational analysis can enhance the use of PEGs in different GI diseases and lead to a non-invasive, cost-effective diagnostic modality that has not been explored before. The purpose of this work was to develop an automated AI model, You Only Listen Once (YOLO), to detect prominent bowel sounds that can enable real-time analysis for future GI disease detection and diagnosis. A total of 110 2-minute PEGs sampled at 44.1 kHz were recorded using the Eko DUO® stethoscope from eight healthy volunteers at two locations, namely, left upper quadrant (LUQ) and right lower quadrant (RLQ) after IRB approval. The datasets were annotated by trained physicians, categorizing BSs as prominent or obscure using version 1.7 of Label Studio Software®. Each BS recording was split up into 375 ms segments with 200 ms overlap for real-time BS detection. Each segment was binned based on whether it contained a prominent BS, resulting in a dataset of 36,149 non-prominent segments and 6435 prominent segments. Our dataset was divided into training, validation, and test sets (60/20/20% split). A 1D-CNN augmented transformer was trained to classify these segments via the input of Mel-frequency cepstral coefficients. The developed AI model achieved area under the receiver operating curve (ROC) of 0.92, accuracy of 86.6%, precision of 86.85%, and recall of 86.08%. This shows that the 1D-CNN augmented transformer with Mel-frequency cepstral coefficients achieved creditable performance metrics, signifying the YOLO model’s capability to classify prominent bowel sounds that can be further analyzed for various GI diseases. This proof-of-concept study in healthy volunteers demonstrates that automated BS detection can pave the way for developing more intuitive and efficient AI-PEG devices that can be trained and utilized to diagnose various GI conditions. To ensure the robustness and generalizability of these findings, further investigations encompassing a broader cohort, inclusive of both healthy and disease states are needed. Full article
