Imaging Test May Predict Patients Most at Risk of Some Heart Complications from COVID-19
Researchers at Johns Hopkins Medicine have shown that a type of echocardiogram, a common test to evaluate whether a person’s heart is pumping properly, may be useful in predicting which patients with COVID-19 are most at risk of developing atrial fibrillation — an irregular heartbeat that can increase a person’s risk for heart failure and stroke, among other heart issues. The new findings, published online May 30 in the Journal of the American Society of Echocardiography, also suggest that patients with COVID-19 who go on to develop atrial fibrillation more commonly have elevated levels of heart-related proteins called troponin and NT-proBNP in blood test samples.
Cutting out the proteins that give SARS-CoV-2 its power
Researchers at Texas Biomedical Research Institute (Texas Biomed) have narrowed down the proteins enabling SARS-CoV-2 to cause disease. Using advanced genetic engineering techniques developed at Texas Biomed, they systematically deleted the genetic code for five of the virus’s accessory proteins, one at a time, to see how each one affected the virus’s ability to spread and cause illness. The research was published online this month in the Journal of Virology.
UC San Diego Health Adopts SMART Health Card for Digital Vaccine Records
UC San Diego Health is now offering a verifiable digital vaccine record to its patients who have or will receive a COVID-19 vaccine. These secure online records, otherwise known as a SMART health card, can be accessed directly from the MyUCSDChart patient portal.
Study confirms the low likelihood that SARS-CoV-2 on hospital surfaces is infectious
A new study confirms the low likelihood that coronavirus contamination on hospital surfaces is infectious. The study is the original report on recovering near-complete SARS-CoV-2 genome sequences directly from surface swabs.
Virus that causes COVID-19 can find alternate route to infect cells
The virus that causes COVID-19 normally gets inside cells by attaching to a protein called ACE2. Researchers at Washington University School of Medicine in St. Louis have found that a single mutation confers the ability to enter cells through another route, which may threaten the effectiveness of COVID-19 vaccines and therapeutics designed to block the standard route of entry.

Biophysical study sheds light on potentially druggable process of SARS-CoV-2 replication
This study investigates how the nucleocapsid protein, or N protein, of the SARS-CoV-2 virus packages the viral genome.
SARS-CoV-2 Worldwide Replication Drives Rapid Rise and Selection of Mutations
The number of COVID-19 variants is growing rapidly, so much that the scale and scope of mutation may pose a threat to the continuing successful use of the current vaccines and therapies. The findings, by an international team that includes University of California researchers, are being published in the June edition of the peer-reviewed journal EMBO Molecular Medicine. The pace of variation of the SARS-CoV-2 virus strains makes plain the threat that rapidly evolving new strains might give rise to escape variants, capable of limiting the efficacy of vaccines, therapies, and diagnostic tests.
Rapid exclusion of COVID-19 infection using AI, EKG technology
Artificial intelligence (AI) may offer a way to accurately determine that a person is not infected with COVID-19. An international retrospective study finds that infection with SARS-CoV-2, the virus that causes COVID-19, creates subtle electrical changes in the heart. An AI-enhanced EKG can detect these changes and potentially be used as a rapid, reliable COVID-19 screening test to rule out COVID-19 infection.
For Transplant Recipients, Third Time May Be the Charm for Better COVID Vaccine Protection
In a study published today in the Annals of Internal Medicine, Johns Hopkins Medicine researchers say they believe that, for the first time, there is evidence to show that three doses of vaccine increase antibody levels against SARS-CoV-2 — the virus that causes COVID 19 — more than the standard two-dose regimen for people who have received solid organ transplants.
AI Predicts How Patients with Viral Infections, Including COVID-19, Will Fare
UC San Diego School of Medicine researchers discovered gene expression patterns associated with pandemic viral infections, providing a map to help define patients’ immune responses, measure disease severity, predict outcomes and test therapies — for current and future pandemics.
SARS-CoV-2 Detectable — Though Likely Not Transmissible — on Hospital Surfaces
