A review of the literature regarding computer-assisted diagnosis of rheumatic diseases is presented. After a general outline of the history and goals of computer programs intended to support physicians in the diagnostic process, 14 systems or projects are described. The scope of seven of these is general internal medicine, and the other seven are intended exclusively for rheumatic problems. The majority of these systems are prototypes. To date, none of them is widely used by physicians. Preliminary evaluation studies and/or independent reviews have been reported for all of the systems. The need for further evaluation studies is recognized, and strategies to carry these out are outlined. Furthermore, the potential usefulness for patient care and education is discussed. It is concluded that a new and interesting field is being developed that deserves more attention among rheumatologists.

We propose a classification method for distinguishing atrial fibrillation from sinus rhythm in pulse-wave measurements obtained with a blood pressure monitor. This method combines recurrence-based plots with convolutional neural networks. Moreover, we devised a novel plot, with which our classification achieved specificity of 97.

Background: These days, various surgical techniques such as trans-anal, trans-perineal total mesorectal excision, and transvaginal natural orifice transluminal endoscopic surgery have been utilized with flexibility, which was not possible before the laparoscopic era.
Methods: From January 2014 to January 2023, 40 cases of c(yc)T4b rectal cancer underwent local curative surgery laparoscopically at Kansai Medical University Hospital. In 25 consecutive cases, we adopted multiple approaches (trans-anal total mesorectal excision, transvaginal natural orifice transluminal endoscopic surgery, trans-perineal total mesorectal excision, or prone position first abdominoperineal excision) to remove the deepest part of the tumor indicated by MRI last as the specimen-oriented surgery.

To investigate the diagnostic performance of texture analysis using multi-parameter MRI in distinguishing between benign and malignant lesions with ovarian-adnexal magnetic resonance imaging report and data system (O-RADS MRI) score 4. A retrospective analysis was conducted of 57 lesions with an O-RADS MRI score of 4, of which 26 were benign and 31 were malignant. Based on the T2WI, ADC, and CE_T1WI, the textural features of the entire lesion were extracted.

Background: Auricular deformities are common in newborns and require early diagnosis and timely intervention. Several factors highlight the necessity of a machine learning-based diagnostic solution: the high prevalence of these conditions, the narrow time window for effective non-surgical treatment, limited medical resources, and the importance of both physical and mental well-being. This study presents a novel artificial intelligence (AI) model to identify and classify common sub-types of auricle deformities, using photos taken with mobile devices.

Traditional depression detection methods typically rely on single-modal data, but these approaches are limited by individual differences, noise interference, and emotional fluctuations. To address the low accuracy in single-modal depression detection and the poor fusion of multimodal features from electroencephalogram (EEG) and speech signals, we have proposed a multimodal depression detection model based on EEG and speech signals, named the multi-head attention-GCN_ViT (MHA-GCN_ViT). This approach leverages deep learning techniques, including graph convolutional networks (GCN) and vision transformers (ViT), to effectively extract and fuse the frequency-domain features and spatiotemporal characteristics of EEG signals with the frequency-domain features of speech signals.
