Critical to managing the spread of COVID-19 is the ability to diagnose infection and define the acquired immune response across the population. While genomic tests for the novel Several Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) detect the presence of viral RNA for a limited time frame, when the virus is shed in the upper respiratory tract, tests able to define exposure and infection beyond this short window of detectable viral replication are urgently needed. Following infection, antibodies are generated within days, providing a durable read-out and archive of exposure and infection. Several antibody tests have emerged to diagnose SARS-CoV-2. Here we report on a qualified quantitative ELISA assay that displays all the necessary characteristics for high-throughput sample analysis. Collectively, this test offers a quantitative opportunity to define both exposure and levels of immunity to SARS-CoV-2., Competing Interests: Declaration of Competing Interest Galit Alter is a founder of SeromYx., (Copyright © 2020.

A rare case of subacute cardiac tamponade developed in a 71-year-old patient after a left lower lobe sleeve lobectomy for cancer. The patient was successfully treated by drainage of the pericardial effusion by a pigtail catheter. The exact cause is uncertain, but it appears to include an inflammatory component., (Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)
