COVID-19 booster for immunosuppressed patients with inflammatory bowel disease

Researchers have published correspondence detailing the reasoning behind providing a third booster dose to patients with inflammatory bowel disease that have been treated with drugs that can reduce the response to the COVID-19 vaccines.

COVID-19 linked to newborn complications

A recent study discusses whether pregnant women with the COVID-19 are at a higher risk for poor outcomes for themselves and their babies.

Small portion of COVID-19 patients infectious long-term

In late December 2019, a novel pneumonia-like lung infection was reported in the Chinese province of Hubei. This, in turn, led to the ongoing coronavirus disease-19 (COVID-19) pandemic. COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is closely related to SARS (Severe Acute Respiratory Syndrome) and MERS (the Middle East Respiratory Syndrome Coronavirus).

More than half of COVID-19 survivors experience "long COVID", researchers say

More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms -; more commonly known as "long COVID" -; up to six months after recovering, according to Penn State College of Medicine researchers.

Study reveals the zoonotic potential of the rat Sialodacryoadenitis virus

A new review aimed to describe the current state of knowledge on Sialodacryoadenitis virus, along with its characteristics and potential zoonotic threat.

Instability in gut microbiota associated with COVID-19-related complications and mortality, study finds

Researchers from Germany recently analyzed saliva and fecal samples from SARS-CoV-2 infected and post-COVID-19 patients and controls while considering multiple influencing factors during hospitalization. This study is available on the bioRxiv* preprint server.

Anti-rheumatic drug as a potential candidate for treating COVID-19

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces inflammatory cytokine storms. But an FDA-approved anti-rheumatic drug, Auranofin, used to treat autoimmune and infectious diseases, may also help serve as an antiviral treatment for COVID-19 infection.

New study finds SARS-CoV-2 causes retinal infection

Can coronavirus disease 2019 (COVID-19) affect the eye? New research suggests the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can enter the eye and infect photoreceptor and retinal ganglion cells. In addition, SARS-CoV-2 infection increases the expression of several inflammatory genes, including the cytokine interleukin 33 (IL33), which is linked to COVID-19 disease and retinal degeneration.

Role of CRISPR-Cas12a visual biosensor in detection of SARS-CoV-2

A new study aimed to develop a novel CRISPR-Cas12a powered visual biosensor for the detection of SARS-CoV-2.

Comparing lateral flow testing with RT-PCR to detect SARS-CoV-2

Lateral flow devices (LFDs) are point-of-care tests that require significantly more time to develop than RT-PCR assays but can be used locally with minimal to no training, some of which can provide results in as little as 30 minutes. However, there have been some worries about the sensitivity of such kits. As a result, researchers from Micropathology Ltd have been comparing the two methods.
