Tranexamic Acid for Shoulder Arthroplasty: A Systematic Review and Meta-Analysis.

Tranexamic acid (TXA) is an antifibrinolytic agent that has been shown to decrease blood loss and transfusion rates after knee and hip arthroplasty, however with only limited evidence to support its use in shoulder arthroplasty. Therefore, we performed a systematic review and meta-analysis to evaluate the clinical usefulness of tranexamic acid for shoulder arthroplasty. A thorough literature search was conducted across four electronic databases (PubMed, Cochrane Library, Web of Science, Scopus) from inception through to 1 December 2021.

Autofluorescence imaging of Barrett's esophageal lesions with additional transformation into spatial images of green autofluorescence intensity.

Background:  Early diagnosis of patients with Barrett's esophagus is required to  implement appropriate treatment to prevent neoplastic disease development. In  this work, we examined the usefulness of autofluorescence imaging as a method to increase the sensitivity of targeted biopsy under numerical color value control with  the additional conversion of autofluorescence images into spatial green autofluorescence intensity images.

Methods: 148 patients were included in the study.
