Lung Ultrasound Score in COVID-19 Patients Correlates with PO/FiO, Intubation Rates, and Mortality.

Introduction: The point-of-care lung ultrasound (LUS) score has been used in coronavirus 2019 (COVID-19) patients for diagnosis and risk stratification, due to excellent sensitivity and infection control concerns. We studied the ratio of partial pressure of oxygen in arterial blood to the fraction of inspiratory oxygen concentration (PO/FiO), intubation rates, and mortality correlation to the LUS score.

Methods: We conducted a systematic review using PRISMA guidelines.

CEACAM6 is a novel biomarker in pancreatic adenocarcinoma and PanIN lesions.

Objective: The purpose of this study was to test the hypothesis that CEACAM6 expression is an indicator of adverse pathologic features and clinical outcome in pancreatic adenocarcinoma.

Summary Background Data: Previously, we have demonstrated carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) to be an oncoprotein that plays an important role in the biology of pancreatic adenocarcinoma. Suppression of CEACAM6 expression reduces tumorigenesis and metastasis in vivo.
