Using Quantitative D-Dimer to Determine the Need for Pulmonary CT Angiography in COVID-19 Patients.

Introduction: COVID-19 has been frequently cited as a condition causing a pro-inflammatory state leading to hypercoagulopathy and increased risk for venous thromboembolism. This condition has thus prompted prior studies and screening models that utilize D-dimer for pulmonary embolism (PE) into question. The limited research to date has failed to provide tools or guidance regarding what COVID-19 positive patients should receive pulmonary CT angiography screening.

Comorbidities in Trauma Injury Severity Scoring System: Refining Current Trauma Scoring System.

The revised trauma score combined with the Injury Severity Score (ISS) remains the mostly commonly used system for predicting trauma mortality, but these scoring systems do not account for the patient's comorbidities. This study aims to evaluate the effect of comorbidities on ISS-related mortality and length of stay. A review of our trauma center's data registry from 2014 to 2016 was carried out.
