Background: Atrial fibrillation (AF) coexisting with coronary artery disease (CAD) remains a prevailing issue that often results in poor short- and long-term patient outcomes. Screening has been proposed as a method to increase AF detection rates and reduce the incidence of poor prognosis through early intervention. Nevertheless, due to the cost implications and uncertainty over the benefits of a systematic screening programme, the International Task Force currently recommends against screening.

Article Synopsis
  • Oral squamous cell carcinoma (OSCC) is a common head and neck cancer that is usually diagnosed late, leading to a poor outlook, and recent studies have suggested a link between OSCC and the presence of certain microorganisms in the tumors.
  • A review of various studies found that bacteria associated with OSCC show different levels of abundance and diversity, and these bacteria can originate from sources such as oral plaque, saliva, and even the gut, influencing cancer-related processes in both positive and negative ways.
  • The presence of these intralesional microbiota plays a crucial role in the progression of OSCC and related disorders, but challenges like inconsistent sampling methods and microbial identification highlight the need for further research to better understand their implications for treatment and

Cross-Modality Reference and Feature Mutual-Projection for 3D Brain MRI Image Super-Resolution.

J Imaging Inform Med

December 2024

Medical Data Science Academy and College of Medical Informatics, Chongqing Medical University, Chongqing, 400016, China.

High-resolution (HR) magnetic resonance imaging (MRI) can reveal rich anatomical structures for clinical diagnoses. However, due to hardware and signal-to-noise ratio limitations, MRI images are often collected with low resolution (LR) which is not conducive to diagnosing and analyzing clinical diseases. Recently, deep learning super-resolution (SR) methods have demonstrated great potential in enhancing the resolution of MRI images; however, most of them did not take the cross-modality and internal priors of MR seriously, which hinders the SR performance.
