It has proved that the auscultation of respiratory sound advantage in early diagnosis. Various methods have been raised to perform automatic analysis reduce subjective diagnosis and physicians' workload. However, these highly rely on quality database. In this work, we developed first open-access paediatric database, SPRSound. The database consists 2,683 records 9,089 events from 292 participants. Accurate label is important achieve a good prediction for adventitious classification problem. A...

Abstract Background Many studies suggest that patient satisfaction is significantly negatively correlated with the waiting time. A well-designed healthcare system should not keep patients too long for an appointment and consultation. However, in China, spend notable time waiting, actual spent on diagnosis treatment consulting room comparatively less. Methods We developed artificial intelligence (AI)-assisted module name it XIAO YI. It could help outpatients automatically order imaging...

Leukemia is the most common malignancy affecting children. The morphologic analysis of bone marrow smears an important initial step for diagnosis. Recent publications demonstrated that artificial intelligence able to classify blood cells but a long way from clinical use. A total 1,732 images were used training convolutional neural network (CNN). New techniques deep learning integrated and end-to-end leukemia diagnosis system was developed by using raw without pre-processing. creatively...

Background Recent studies have suggested a relationship between gut microbiota and non-alcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH). However, the nature direction of this potential causal are still unclear. This study used two-sample Mendelian randomization (MR) to clarify links. Methods Summary-level Genome-Wide Association Studies (GWAS) statistical data for NAFLD/NASH were obtained from MiBioGen FinnGen respectively. The MR analyses performed mainly using...
