Sex-specific incidence of hepatitis B virus flares among Bcr-Abl tyrosine kinase inhibitor users in Taiwan.

Background: The use of Bcr-Abl TKI was found to be associated with hepatitis B (HBV) flares, with a more profound risk observed in females. This study was conducted to characterize the clinical features of patients with HBV flare among Bcr-Abl TKI users, to estimate sex-specific incidence rates of HBV flare, and to evaluate potential cumulative effect of Bcr-Abl TKI.

Methods: Bcr-Abl TKI users with chronic HBV infection were identified from Taiwan's National Health Insurance database.

Deep learning-based classification for lung opacities in chest x-ray radiographs through batch control and sensitivity regulation.

In this study, we implemented a system to classify lung opacities from frontal chest x-ray radiographs. We also proposed a training method to address the class imbalance problem presented in the dataset. We participated in the Radiological Society of America (RSNA) 2018 Pneumonia Detection Challenge and used the datasets provided by the RSNA for further research.
